The 4 Most Common Motorcycle Crashes & The Reasons Why

[@Gambo916]

My first guess for the #1 common cause of a crash was 'a lack of talent'!! I had a fair few slappers on my bike when I was younger.......but now that I'm older I can't be bothered anymore and just tell them to catch the bus instead. Seriously.....great vid Dave, very informative. Thank you.

[@MikMech]

The main problem with Motorcycle Tyres, they never look underinflated... Thanks for your knowledge and wisdom.

[@Oooooska]

Been rinsing through your content these last few weeks. Riding a few years now but the learning never ends and your info and advice is very informative! Thank you!

[@raymadani270]

Thanks Dave. you saved a few lives in the process

[@JeffJeno1000]

Really it all comes down to bike setup, suspension settings, tyre type and pressures, and riding to skill and surface conditions. Good to see an informative video and a person passing on knowledge 👍

[@peterinfante6187]

Great content, Dave! Keep these classes coming. Haha. Love the classroom feel.. It may be basic to some but to others it can install valuable information to process in their brain by being a better and safer rider. Win win as you say..

[@catalystreactionsbw]

Thank you Peter for the kind words - trying to appeal to 80% of the audience as a whole as I know 100% is not possible even though I aspire to that!

[@JohnnyDoeDoeDoe]

It's insane that my only motorcycle racing crash is #1 and reason #1 on your list. This might be my favorite video of yours yet!

[@scottparkhurst7259]

Very nicely done. Explained simply and where you can understand. Thank you Dave.

[@DB-so8zc]

To tight of a chain can be a cause of a highside. I love learning new things. Great info and explanations of cause and affect Sir!

[@interlochen318]

Can you please give me a link to other studies that prove to tight of a chain can cause a high side. Any help would be greatly appreciated.

[@wirenut3020]

Can you do a series on how to set and or troubleshoot geometry? My Honda VFR 2006. I replaced my rear shock and upgraded my front forks with new springs and valving. The shock is ride height adjustable. I returned my fork height to the factory specifications and eyed up my shock length with the new one. They seemed equal but I had to add 2 washers to the top of the shock to prevent the remote fitting from contacting a fixed bracket on the bike(this added about 2.5mm to the shock length)The bike seemed okay at first but the shock seemed too stiff as setup by DMR Suspensions. I discovered that there was no static sag. I took 3 turns out of the rear shock spring and ended up with 40mm of total sag and 12mm of static sag. The bike didn’t want to turn as readily. I lowered the front 6mm and ultimately raised the rear height maybe another 2mm. It feels good but how do I vet my changes for safety reasons? How do I know it’s not biased on its nose now? What’s the process for setting up geometry on a street bike? I’d love to see a video on your paid channel.

[@Angel-HC]

I rode my friend's new to him R6 back home for him which was about an hour and fifteen minutes. I foolishly forgot to bring my pressure gauge and pump to check the tires. The bike felt all kinds of weird on turn in. We got it back home and the tires were both below 20 psi. Set them to ~32/36 and that definitely improved things. But, on six year old rubber I'm recommending he gets a fresh set as well before he does any real riding.

[@wobblysauce]

Buy anything, and you put fuel in it, check the pressures, it doesn't need to be accurate but even ballpark is good and the guages are never that far out.

[@halfblindmotonut]

"I had to hit the kill switch and let the bike go"....Proof Dave is immortal lol.

[@atmerkakis]

this is great info, i took recently Dave's suspention tuning, and its so valueable

[@Dani2wheels]

Dave: I knew #4 immediately (because you told me!)... Years ago I slightly changed my geometry, had a huge slapper, and you told me through Facebook that I was driving the wheel into the ground, causing the problem. Thank you so much, I changed it back and we're back to beautiful, no-stabilizer riding ever since.

[@X2hedX]

I have this issue on a naked bike, do the front forks need to come up slightly then?

[@southend26]

I check tire pressure, but some of the dumb stuff I've done over the years... I've been right there with the rider from the Laguna Seca clip.

Thanks for posting this, always useful info!

[@rabukan5842]

Great stuff here Dave! And you are right in not disparaging the young lady for having such low tire pressure. Has anyone else explained it to her? Now she knows, and good for you. I know many riders who also don’t think about tire pressure, correct suspension, trail braking, proper lean angles in cornering, etc. The point is to inform, and beating up on riders informs pretty much no one.

[@catalystreactionsbw]

Thank you for taking the time to comment and I appreciate the support. Spreading understanding has been my mantra for decades so riders can help riders anywhere any time hence my request for all to "pay it forward".

[@scottthompson7009]

[@catalystreactionsbw]

With the broadcasts I did with Streamlounge.io on MotoGP and World SBK races, I take a lot of time to show how the crashes happen to explain them in detail. A crash collage of high sides and low sides might be an interesting video to produce.

[@User-cc6cq]

Back in the day, while rolling on (well, more like just whacking open) the throttle on a borrowed 1974 Kwaker H2 Mark IV 750 triple...experienced quite the tank slapper/head shake...had my full attention for what seemed (in the moment) like an eternity! 😀

[@catalystreactionsbw]

Thankfully you did not have the first year (1972) that did it as you got into the power band. Worst experience for me was on the original Z1 900.

[@justinspencer1379]

Can't stress the importance of sharing valuable knowledge. Learning to ride and never heard anything on the proper suspension setup. only wish I found DMT earlier. Riding my motorcycle has felt like wearing the wrong size shoes for too long!

[@PleatherJacket]

I got high sided to next year recently. Cold tires cornering with debris on the road. Wear riding boots people. I’m out 2 feet for a few months.

[@Doober50569]

@11:10 Hey Dave I want to point that my honda shadow did the same exact thing between 45-40 mph, But i figured out that it was 100% an unbalanced front tire. I had replaced the tire (due to mileage not this condition) and it magically disappeared. I no longer have the issue.

[@catalystreactionsbw]

Thanks very much for sharing your experience to help others!

[@motorcycleintenerife7104]

Video i watched over and over, one of the best explanation what to be aware of

[@catalystreactionsbw]

Thank you very much for posting a reply! I'm honored that you found this video of great use and relevance.

[@colouny]

I have to add that bad sterring bearings can be noticed pretty early by uneaven front tire wear. Steering bearings in some cases can go bad even by hitting deeper potholes. This even feels when entering corner properly and finishing it in front of oncomming traffic unintentionally, this ads unconcious need for braking mind corner to drop speed. Even sligtest damage to steering bearings has an effect on driveability, and unexpected beahaviour of the bike.

[@impaledface7694]

Highsided about 1 or 2 weeks ago on my cruiser. Hard/old tire, higher pressure, cold tire, and the rain was enough. Pretty sure I was spinning and countersteering in the beginning, then it caught and I was on my butt facing against traffic. Good learning experience. Running lower pressure on that bike and only riding on dry days. No major injuries since it was under 20mph probably around 15 or 10.

[@marcosgarcia11084]

Awesome video sir dave moss....in regards to low tire pressure, I literally check tire pressure every time I go out. I have a 2014 Yamaha r6, what do you recommend? Just normal city riding. Once in a while go up the 120 to sonora or up the 88 to Amador.

[@catalystreactionsbw]

Thank you! Depends on your weight, speed and carcass design of the brand you purchased. General go to as a starting point is 34 front and rear or 36 rear.

[@StevePhillips76]

Great video, I can see a few things that I can improve on. Thank you!

[@kennethengstrom9261]

Great info for all motorcycle riders👍🏍🙏

[@Carby4SZK]

what measurements are you talking about when you refer to a tank slapper after a crash? I also have a Suzuki Bandit 600 S that does the same thing and the mechanic had no idea what it could be. Checked everything else. 😅

[@catalystreactionsbw]

Setting the front wheel visually perfectly straight. Then measure 9-3 on the clock face to see if the forks are out of alignment.

[@Carby4SZK]

@@catalystreactionsbw thanks. I will try measuring this.

[@DaBinChe]

I used to check tire pressure every ride, then it became every other ride, then once a week, now once ever few weeks. I can feel when pressure is down almost 5psi.

[@SniperSnake50BMG]

With electric Motorcycle I almost always check tire pressure. Pressure in the teens means 20 to 30% less range

[@impalaSS65]

Tank slapper in low speeds reminds me of my zrx1200. Never a problem including 240km/h on bumpy bends. Then I picked up a three-set of Giwi hard cases and went back home with it. Still no problem at 220km/h but letting the bars go while decelerating from 70 to 45km/h it started to wobble increasingly. The fork bushings were shot and replaced, the front wheel bearings where replaced, the head stock bearings felt fine and so did the swing arm and rear wheel bearings, but they will be replaced this winter. It still feels a little wobbly in tight turns, faster than walking, particularly with some load in the top box (the side cases only on vacation). It needs some speed to be noticed. Standing still balancing, then going slow with full steering lock, will not provoke any wobble. Full confidence going fast though. It goes where ever I point it. It might very well be crashed at some point. "Custom paint job", crash sliders in matching color. Replaced blinkers, smaller aftermarket.

[@dragonniteIV]

So if your handle bars wiggle (not too much) on low speeds there is something wrong?

[@catalystreactionsbw]

There is something that needs to be addressed - and the root cause of that should be identified. Low speed wobbles generally create very quick reactions that are very forceful and that can lead to all kinds of problems.

[@MrLeo3D]

I've got an apparently stock Bandit 1200 k3 last year, how can I check the front suspension to know whether it has been crashed or not?

[@itllkeal]

Heck. I'm 44years old and I can't tell you what pressure is in my tires right now. However I did have a new front installed professionally last week

[@bp7178]

I bought that tire gauge just because I saw Dave using it a year or so ago.

[@IDK123LOL]

The 2021 MT09SP 6 Axis imu will prevent all of this, pls information

[@catalystreactionsbw]

Traction control in all formats will make a difference BUT it is a double edged sword. It can work well and save a crash but it can also create a high side if the tyre gets loose.

[@TechItOut]

I can't find anywhere in South Wales UK that can competently check and adjust my Ninja 1000 SX suspension. Anyone know of somewhere?

[@catalystreactionsbw]

Do you have tools? I can help you in person via email or the web.

[@sanxi34]

Low tire pressure; I check the pressures every refuel. I’m already stopped and the tyres ain’t ice cold but they are not hot either =D. It takes 15seconds unless you need air and then you’ll b3 happy you checked it.

[@mbag012]

Solid gold content sir

[@vito1064]

Tank slapper can also be caused by the steering not being free to move quickly to let the bike straighten itself (steering bearings or damper too tight) and worn out steering bearings (the balls or rollers deform the races and they want to fall back into their "hole")

[@Mr.Meogie]

Wheels misaligned biggest cause of wobble. And also low air pressure.

[@ItsSaiyan]

Also this is considered common Knowledge for the people i ride with very important to understand what happening with the bike at all time

[@PaulMappud]

My only tank slapper was hitting a cat's eye as I swung out to overtake with a big handful, I was just a passenger but it calmed itself luckily, a new pair of breeks was needed and I bet the folk I tried to pass had a bloody good giggle...

[@tysonkampbjj]

It seems like grabbing a handful of throttle exiting the turn is more common than it was 20-30 years ago. I suppose because there were no electronics, the top class was still 500 two strokes, and people just high sided a lot more.

[@billyjoeperkins8145]

check out dewalt cordless air inflater ......dial in the psi number and press play.....it runs up to the selected psi and stops....no need to play with air gage

[@bigwave_dave8468]

Well if you're splitting hairs..upon seeing the title I was going to say 1) low-side, 2) low-siide, 3) low-side 4) high-side...I agree with your list but have never personally experienced a tank slapper (good dampers?)...could add to that 5) target fixation/failure to avoid incedent in front of you. Of course I've never had a problem with my suspension but then again, I had a great tuner :-)

[@yarpenzigrin1893]

Yup, I figured out it would be lowside and highside. You split lowside into two subcategories though.

[@TheRandomBikers]

I run 23r and 26f cold pressures for street. Works perfect for me tonnes of grip.

[@Learning_3d]

I have done #1 and #3 (when over a bump on corner exit and was on POWER!) 300 pounds in the air like an eagle.

[@mattm9087]

Even when u buy a used bike check tire pressures chain lube everything before u hop on. Can't tell u how many bikes I've looked out where the bikes been neglected for too long. We went to pick up a bike and the chain was soooo dry you could hear it ticking along from 20 yards away. When I asked the girl when she last cleaned and lubed the chain as my buddy clacked away on his test ride her face went blank and she was like oh ummm probably not since I bought it a couple years ago. I didn't know I had to do that lol. Some other dude tightened his chain as tight as a piano wire and cleaned it bone dry. It sure was shiny but tight as hell and dry as a bone. My brother asked him what was wrong with the chain and he said oh I thought that was how it was supposed to be lol. Seen ppl with tires so low its almost laughable how they didn't think or care it was a problem. Accidents waiting to happen. Plz check ur bike to make sure it's safe to ride.

[@elobiretv]

Bought a used bike a few years ago and it had almost 0psi in the tyres because of a small leak. Was just about to do the hour ride home before I thought about checking the pressure with the pump in my brothers car. Another bike I bought also had the chain as tight as possible.

[@mickleblade]

I thought number 1 would be panicking on corner entry, and then just drifting wide 'cos you couldn't make yourself lean a bit further to make the bend.

[@233kosta]

My rear tyre has a slow leak. Looks like a nail in it or something. I reckon I rode like that for maybe a week until I noticed my back end going a bit squirrelly and checked. Damn thing was silly low, and you could NOT tell just by looking at it or squeezing with your finger. So anyway, now it's a trip to the compressor as soon as I leave the house :P

[@catalystreactionsbw]

A good case for checking pressure before each ride so you do not get an unwanted surprise!

[@233kosta]

@@catalystreactionsbw Absolutely! Lessons learnt and all ;) But also a good case for learning to be a smooth, attentive rider (work in progress...) and getting a good feel for what the bike *should* be doing (even more work to do here...) - that way you can maybe catch things like this before they get you in trouble

[@ZeroBoostBuick]

Tank slapper aka "Widow Maker".. with my R6 (2010) I can let go of the handle bars at any speed including 250+ KPH (155 mph+, I have done it) and it goes straight like an arrow. While my other bike a 1985 Maxim-X (Power Cruiser bike with FZR-750 engine from factory only built in 85 & 86 ) wants to kill you when you let got of the handle bars, and that's because previous owners crashed it and frame was bent. Take nothing for granted. If it's not right, you must fix it before you get hurt.

[@TheRandomBikers]

Tank slappers are fun, I wheelie on corner exit just for the tank slapper thrills haha

[@andrewstambaugh8030]

I was surprised tire pressure didn't show up on tank slapper. Can you comment on that? (I've traditionally heard that tank slappers tend to occur when someone ignores tire pressures for a long time, and that it can even ruin a set of tires so that they are always prone to slapping) PS I like that your entire list is clear and we can easily see how to address. I expect it will help me help someone at some point.

[@catalystreactionsbw]

Generally tyre pressure is for the most part monitored relatively accurately. To get a tank slapper the rear would have to be 6-10psi below recommended to cause the balance of the bike to move rearward quickly.

[@andrewstambaugh8030]

*I'm not going to be checking my tires 3 times a week but it is reasonable to check them: *every week or every other week if I'm riding a lot *before any long trips *when weather significantly changes (This is also what a do with my car, and I drive that in a way that I notice if my tires have lost 4psi)

[@233kosta]

I did nearly high side once... Yeh, no more corner exits under power in first gear for me :P

[@foolspeedahead]

[@foolspeedahead]

Also, very standup of you guys to say not to trash that gal in the comments. We all start somewhere and with different influences. Hopefully she takes this tip and stays on top of her tire pressure.

[@glennranger4091]

Smart man!

[@jameskirk3]

Number 1 cause of crashes around here are the decreasing radius corners wiith debris on them, and banking that is terrible. We dont have freeways here, just backroads and 2 lanes. A lot of sharp corners that arent well traveled or maintained. We do have a lot of riders come through though because of the lakes and rivers.

[@catalystreactionsbw]

Thanks for sharing. What region/area are you talking about so other riders can be diligent?

[@_MotoMatt]

Rode a demo bike mt-07 and it was the first time I crashed at a track. Low side on corner exit for all 3 reasons. Even though I took the same corner harder on a ninja 400 & r6

In all my years of riding. Full dress bikes are the ones I see go down the most.

[@manjucs2331]

No expert on road please give examples through videos when you explain. Thanks

[@jeremybly]

Did you say that you hit the kill switch and let the bike go? You actually do that? Doesn't seem possible to me but what do I know.

[@catalystreactionsbw]

After 25 years of riding and racing, yes I have the time to mentally realize that I am crashing, I cannot save it and need to hit the kill switch. Practice and time served means "time" slows down a lot and that really makes a difference in knowing what is happening with tires, grip and handling.

[@jeremybly]

@@catalystreactionsbwI understand what you are saying. That's pretty amazing. I've been in a few crashes and I generally like to curse instead whilst it's happening lol. But I think I'll try to remember the kill switch instead. But I'm never going to be at your level of experience so we'll see.

[@SK-tr9ii]

What's a tank slapper?

[@catalystreactionsbw]

When the handlebars violently go from side to side after a large impact through the suspension (manhole cover, pothole, steel plate over a hole etc). You fight to get the handlebars (aka front wheel) back in line.

[@RobertNixAlternativeArtist]

Hope that lady will get an air pump-everyone should have their own portable air pump-I use a high quality bike pump for all my vehicles and that even includes my bicycles!

[@T3MPTAT10NS]

Last reason for a high side was backing it in. But pros do it all the time. Bit curious on that one.

[@catalystreactionsbw]

Pro's do that by keeping the weight on the front tyre while the rear wheel continues to spin as they travel forward. During a high side the rear wheel stops spinning, grips and then launches the rider.

[@superbarnie]

I have a doubt on the tank slapper (radial twist).. and this was unique to Kawasaki Ninja 250's 2010 or 2012 year. from day of purchase speed of 50Mph (80kmph) and I remove the hand and it shakes and when it reduces once I gain more speed or reduce the speed below above mentioned speed... I did ask other riders they say that tyres are at fault ( i was skeptical) 2yrs into using baby ninja I sold it ....

[@catalystreactionsbw]

If you purchased the bike 100% new, this is very odd. Normally we find the rear wheel is not correct with alignment and once corrected, the shake was removed. Low tyre pressure can also cause this.

So what is Radial twist ? Is that when the front tire is out of alignment with the rear tire ? How would that be checked ? Any help is appreciated. Also to tight of a chain causing a highside ?

@@interlochen318 When a bike hits the ground, the engine moves in the frame, forks turn, triple clamps get tensioned as does the swing arm. All that movement moves parts either side if the vertical axis = radial twist.

Chain tension, cleaning assessing etc are all here on my channel: kzbin.infosearch?query=chain%20

[@marcusgeorge1825]

Dave, I agree with every point you have made. These are all caused by bike settings and rider input. Yes? As you’ve combined both the track and streets, then for the very first time I have to disagree with you (purely based on the combination). On the road you have so many other factors that come into play that you don’t get on a track. I won’t list them all as I’m sure you know where I’m leading. Yes, most of these other factors can be avoided if you ride well under your capabilities and leave 40% in reserve for the “oh shit” factors. However some, that you haven’t listed can be unavoidable.

OK so biker it's oz had and off last week. And I had my first of in 26 years of riding last week and this week dave talks about crashing.... What are the odds. I'm not sure what happened there are 2 scenarios. Firstly it was around midnight, the weather had come in and standing water and flowing water the roads had become rivers. Scenario 1 learner driver first time in these conditions side swiped me as I passed. Scenario 2 traversing through road works with white line painted black and the back lost traction and spat me down the road. 80 miles into 100 mile journey the bike had been planted even in those condition and the first 60 miles was a lot heavier rain and water on the road. The section of road was dual carriage way and has major road works going on in preparation of a new river crossing. This section is also unlit. One moment I'm upright and going straight the next there's a thump and I'm sliding down the dual carriage way on my right bum cheek. Which is a nice shade of deep purple atm. So new waterproofs needed, helmet and boots as I torn 3/4 of the sole of the right boot. What really has my jogging going though is the rear stepped out to my left but all the damage is to the left hand side of the bike?

[@andrewstambaugh8030]

(edit: re-reading your comment, i originally thought you were speaking for street. now I see your comment is still directed at track) Street: I've seen and heard of far more crashed due to timid fear causing them to freeze than overcooking/ambition. I've personally know far too many riders who quit because they never went out enough to get familiar, so every time they went out was like a brand new/unlearned skill. They'd ride 1-3 times in a year, come out with the group on an easy tame ride, and nearly run off the road because they panic-froze when they thought they wouldn't make an easy corner at an easy speed (because they are afraid to lean, and never ride enough to get over that fear).

The one that I see the most, is due to locking the rear brake in a panic situation!!!

[@HangHe2key]

Hey Dave, in my opinion you are a bit off on this one, the most common crashes on the street are caused by the environment and rider errors. Like: 1. You are not seen or your speed is incorrectly judged by other road users 2. Target fixation and "fight or flight reflex" -> muscles tensioning -> can't hold your line 3. Bad road condition or obstacles on the road 4. More ego/speed than skill/brain or you are getting carried away by speed

Biggest factor in bike accidents is going too fast for the road conditions. Young bikers think they are immortal and love riding like it. They will speed through traffic and then act surprised when they end up hitting a car or losing control of their bikes.

[@dirttdude]

No, the most common reason for crashes is speed to high for jumps, speed to low for jumps and collisions in berms

[@alexrice1451]

How about people slaming their brakes for no reason going 50mph preforming an unsuccessful quick stop and highsiding/ launching yourself on the roof of the car who slam on the brakes in front of you after your front tire hits the person rear bumper

[@jimmycakes7158]

Car cut across the whole exit from the outside lane, I went straight into his side, I felt like I couldn't do anything he was on me in a second

[@q36spacemodulator]

Perhaps this should be clarified, street or track. Although many points cross over i would have thought things like , assuming someone will give way to you, sitting in a drivers blind spot on multi lanes, road positioning etc. would be major causes of accidents on the road.

[@okboomer1241]

Motorcycle crash stats are completely distorted by underreporting. Nobody even knows a crash happened unless it results in a police citation/report or an insurance claim. Hence the term "murder cycles." I have seen or experienced 12 crashes over the years. 11 of them we picked up the bike and rode home. Think about all the crash vids on KZbin, like the rnickeymouse channel. Vast majority never involve the cops, and most likely the rider won't file an insurance claim either cuz it will just make their rates go up. This is the exact opposite of automobile crashes. Cars don't fall down, so to qualify as a crash you've got to actually hit somebody else's property. Thus the vast majority of car crashes are logged by law enforcement and easily catalogued by statisticians. If you watch all the crashes on the rnickeymouse channel, all of them are riders falling down of their own accord. I can only think of one exception where a guy target fixated and ass packed a pedal biker, but it was still the motorbiker's fault.

[@q36spacemodulator]

I don't know where you live but here all accidents on a public roads have to be legally reported and if the cops turn up like they should you will be breathalysed. You tube is not the real world. After 50 years of riding roads, tracks and off road, 25 years of that for a job, many motorcycle courses and 5 years collecting statistics on bike accidents I have a fair idea what causes accidents. The points he puts forward are relevant to both track and street but the presentation seems directed towards the track. If you think riding on a track is the same as on the street you need to do some research they require very different skillsets in many ways.

[@okboomer1241]

@@q36spacemodulator I too have 50 years of riding experience, roads track and off-road, but only 10 of it for a job, that lead me to conclude upwards of 50% of all street/road crashes go unreported and thus uncounted for statistical purposes. Perhaps the MIC or AMA could do a survey of 100k riders asking if they've ever been in a crash that wasn't recorded by law enforcement or insurance company.

[@nerychristian]

​@@okboomer1241 The only time I ever dropped by bike, it was a rainy day, and I fell while entering the freeway on ramp at around 15 miles an hour. The bike didn't get damaged other than the foot peg and a slight scratch on the tank. I never reported it.

[@A.Dude.]

I stopped checking tire pressure about two years ago BECAUSE I INSTALLED A PERMANENT MONITORING SYSTEM LOL!!!

[@catalystreactionsbw]

Work smarter not harder right ?! :)

[@A.Dude.]

@@catalystreactionsbw Absolutely!

[@aricmoto]

The difference between the average female rider and most male riders; that young lady will now regularly check her pressure, but most guys will continue to not check it.

[@nerychristian]

You overestimate the female mind. My mom is in her 50s, and still refuses to check the tire pressure despite being told to do it regularly.

[@---yx7ti]

Got hit by an illegal u turn driver 2 weeks ago

[@jakebsellin]

Running wide is not in the top 4?

[@catalystreactionsbw]

It is not. Generally riders get out of the throttle long before they leave the track surface as an act of self preservation by their lower cortex. Often done prior to thinking about it....

[@jakebsellin]

@@catalystreactionsbw Oh gotcha, yes I agree on the track. I was thinking as far as the street. Great video as always! Very informative!

[@catalystreactionsbw]

@@jakebsellin Ah, noted on your POV. I can see why you thought it would be on the list.

[@andrewstambaugh8030]

For the street, running wide is the #1. Bret Tkacs did some kind of government training with realworld statistics on it.

[@jakebsellin]

@@andrewstambaugh8030 This is why trail braking is so important, especially on unfamiliar roads!

[@elmerfudd1086]

These are all race track crashes. The most common motorcycle crash , in fact 67 percent of all motorcycle crashes is someone turning left in front of them.

[@kenwoolf]

1.17 bars in the front wheel and she drove that? How the actual fuck? If I am off by 0.2-0.3 bars the bike feels to be buckling under me in every corner. Altough I am pretty heavy, so that might be my problem.

[@catalystreactionsbw]

Perspective is weight and ability combined.

[@kenwoolf]

@@catalystreactionsbw Yeah. I am still only a beginner when it comes to riding. Probably that's why every minor change on my bike feels like I am riding a different one. :D

[@andrewstambaugh8030]

@@kenwoolf Every minor change on a bike is noticeable. That shouldn't go away with skill, it should become more noticeable. In an offroad even, we rode a friend's klx250 which he didn't care for and was ready to sell. after trying it, I freed up the throttle (cleaned and set some cable slack) while a motocross friend lowered tire pressure and bled the suspension. Everyone after that said it was a completely different bike and he no longer wanted to sell it. That transformation was all free, except a little wd40. (and we didn't do anything complicated eg alter main geometry by raising/lowering forks)

[@impalaSS65]

I can relate to that nit wit girl. I went on checking my "new to me bike" almost every day, until I got bored and fell out of it. Had it at a bike shop unrelated to tire pressure and they put me to shame for having ridiculously low pressure on the rear tire. Apparently I am - contrary to my self image - NOT attacking the curves like Marquez.

[@Motosapien46]

I say this only from having foolishly done it myself. I'm sure when she brought the tire pressure up it was a whole new bike that she didn't have to wrestle the bars to turn. I bet it was a fight at low speed!
