very informative thank you.

If I have a toque figure from a dyno run with stock gearing and it's say 90 foot pounds if I gear the bike down say -1 on the front and +1 on the rear. Will the torque figure change on the dyno? I know the outright hp figure won't but I'm unsurs about the torque.

A bad start. They were not a pair of pliers.

My new E Ride Pro SS 2.0 E Moto e bike has a 19 inch rear wheel and 55 tooth sprocket stock. I'm going to a 16 inch rear wheel and 60 tooth sprocket and Warp 9 is building the wheel for me. Now I'm "re thinking it" and hoping that's not to "RADICAL" of a change, going lower diameter tire size plus 5 tooth larger sprocket! I'm not worried so much in losing top end speed as I mainly just trail ride and hills, hills and technical stuff. Any thoughts or opinions would be most welcome! Thanks for the advice and great Video! : )

I haven't watched the whole video yet but I had a 400 it was during the Gap years before they discontinued the big rebels. And I went from a 5 and 3/4 rear sprocket to a 4-inch rear sprocket completely forgetting about the circumference of circles and I went from doing 80 mph top speed to about 140 I'll leave it to you to look up pie and all that stuff and do the math but it's a real thing that works and I didn't lose any of my acceleration which is what really astounded me I actually accelerated faster

Great Video thanks.

I wear a hard plastic one I wish it protected my back more I am looking into buying one with back protection and chest I want something that protects my shoulders too because I have got thrown off and landed on the my shoulder.

Hello I need Help , I just Buy a Honda crf 300 l ,Just transform Supermotord with original sprocket 14 -40 ...I need more speed ...which will be better change

This is apropos of nothing, others have made good comments, but should you gear your race bike to redline in top gear at the braking point of the longest straight?? Discuss

I just dropped 9 teeth on my rear

How long do you leave it to dry once you’ve oiled it?

Good stuff. Another key factor is CE level 1 vs. CE level 2. Level 1 is just for off road, while 2 is far better protection for better survivability. Also, many Amazon products aren't CE rated at all. They are basically cosplay items, so buyer beware. Cheers!

What? Its correct that increasing front tooth or decreasing rear tooth reduces top speed and makes more torque. But u got the ratios all wrong. I reduced 4 teeth on the rear sproket once..

Dude thx for the info I don’t care if u fucked up the math or terminology what I really wanted to know was real your life experience with going from 51 to 50 on CRF rear for all the same reasons you did. 👍🏼

It dose not increase power to the rear wheel or torque. It increases engine rpm and therefore you're running in more of the more power band or and more torque from the engine because the rpms are up higher to start with. You should leave your front sprocket alone because it can add stress to the bearing. Going up a tooth or 2 for street and up to 8 for dirt. If you're racing i'm just not even going to talk about it. It more complex on many different subjects for racing.

anything is better than nothing. a buddy went down in a 25 mph curve (street riding). it was 95 out so we had t-shirts, jeans and running shoes (he had leather street boots). it was bad, could have been worse. i started wearing the motocross chest/back chest protector and i attached elbow guards to it. i wear the motocross knee/shin guards also. this is for summer. in winter, i will go to a jacket with armor and will continue to wear the knee/shin guards. if he would have had on what i wear now, he would have came out of it much better

Steroids

Thanks! Straight forward.

What about straight-line ruts? What should your body position be? What if it's REALLY sticky? I recently went through a straight-line rut (standing position). I picked a line, looked ahead, went fast, and my wheel just dug in like super glue and I went flying. Really shook my confidence. What did I do wrong? Thx 🙏🏻

Great video man. This helps make a decision on these for sure. Cheers

Horrible video, full of errors.

vid is 2 years old but damn you explained it perfectly

If you do the division the other way the numbers come up with your actual ratio. for example 15 front 45 rear. 45/15=3, therefore 3:1 ratio. This means 3 revolutions of the primary sprocket to 1 of the rear. Just my 2 cents and is easier to visualize.

Where’d you get the partition?

Hes a weight lifter not a mathematician 😅😅

Careful with terminology here, quite confusing for many people. When he says "faster" he means top speed, but it may accelerate slower which would be called "slower" in another area. Really need to use better terminology. Talk about top speed and acceleration, not "faster" or "slower".

Hi so I have an 07 Kawasaki Vulcan vn900 classic and want to put a aftermarket rim 240 40-18 with a custom pulley. The OEM pulleys. Is 34 front and 62 rear how much teeth can I drop on the rear and still function without messing with the front? If that makes any sense 🙏🏼

Do not throw your money away changing the sockets. This will only make 2 results: 1. this will improve starting off (launching) 2. this will increase your RPM in top gear at highway speeds. Changing the sprockets is changing the final gearing on your cycle. Changing the final gearing means nothing. What really matters is overall gearing. Overall gearing is everything from the engine to the rear tire. Overall gearing is a affected by these areas: 1. Manual Transmission 2. Drive sprockets (final gearing) 3. Tire size (actually have to change rim diameter to change tire size much) It is a very common misunderstanding that changing the sprockets will mean you'll always have lower gearing. That is not true. You have a manual transmission. That allows you to have what ever gear ratio you want. If you like the power of low gearing then don't shift until redline for all I care. Shifting at redline is not what you really want unless you are drag racing. My point is you can decide how high you want your RPM to go before shifting. If you like low RPM for fuel efficiency shift early and keep your RPMs low. Once you get in top gear you can't shift up any more. That's why I say changing the sprockets will affect the RPM on the highway.

Glad to see he’s putting his community college acting classes to good use. Without the yammering and 5 minute into I might have stuck around to the end..

Nice race number 🔥

Both footage of riding and learn as you go videos like this one with fan. I to am just now getting onto hard enduro

Id like to hear your 1 yr review. I think these are for me. I have hyper extended my knees on my yz250r, one knee i had to reconstruct surgery. My ins paid for cti fitted brace but it never felt good fit and it slid down my leg often while riding. Plz do a 1yr review

1:54 No! You are not increasing the power. You are increasing the torque and reducing the angular velocity by the same amount. The power remains the same. I left right there. You should leave too. There are many serious channels out there. This is not one of them.

The way I see it gear is replaceable; the body is not.

Most chest protection is just for roost on a track. If you're not on the track, they aren't really useful. Off the track, a protector should not only be more robust but should include shoulder and elbow protection. I always wear a full body armor jacket with an integrated kidney belt.

250 xc... that's a wild cross-country bike....

Geez boi put them guns away my wife is on here 😂

Especially in the front

Not much difference to go 1 tooth on the back sprocket. Big difference 1 tooth on the front sprocket

can u post some biceps exercises?

What happens to your speedometer reading if you change sprockets?

Yup, this video solidified my choice. At 59 years old, I’m not competing, just joy riding, with a busted up old body. I’ll adapt, I’m getting some hard armor front and back. It’s actually pretty simple, I’m tired of pain and starting to fear death.

Im riding since 20 years... Tipp: 1. Take on your chest protection 2. Take your strongest friend. 3. Let him punch you hard in the chest. 4. Take the protection off 5. Let him punch again... - Now you know your chest protector works ;-)

Man good video.. but that "leeever" is killing me.. "lev-ver".. there that's better.

ive grinded 4 sprocket tooths off with my angle grinder and the bikes not faster wtf?

So i went from a 14/41 to a 14/43 i changed the chain and sprocket out becuase the old ones looked worn and my chain kept loosing tension. I habe a 2018 ninja 400. Now with the 43 tooth in thebtear i get overrev around 6k in every gear so is the sprocket my problem or not because ive already bought a new clutch

Those biceps are absurd bro. The ratio of forearm to bicep is .26

Speaking of “gear” , are u natty or naw? Your bicep is the size of my dome piece .

OMG BRO! Why are you spreading bad math!?!

better to add teeth to the rear sprocket, you get more torque and less stress on your engine
