Why YOU Need Lightweight Sportbike Wheels

I just shed a bunch of rotating mass off the 2016 Aprilia RSV4 RR by ditching the stock Cast Aluminum wheels for the Factory Forged Wheels. WOW, what an improvement. Worth every penny.
Let's dig into how much weight was shed and how the bike performs.

You only will feel the difference at the track. On street riding, it’s very minimal feel... But, good find.

[@luvs2race370]

Some Ohlins suspension and you'll officially have an RF, only better looking...Lol! I love your vids man! I've been subscribed since I started shopping for my '17 RF. Watching your vids actually helped me pull the trigger. I bought the bike at the end of April and have logged about 2000 miles so far (I'm in Ohio, so don't have quite the weather you guys have) and I haven't had the first regret. Absolutely love it. What type of ECU work have you done since you added the exhaust to your bike? I have the Yoshi Race Titanium coming for mine and am a little torn on what direction to go with the ECU. There's just not that many options for the Aprilias considering how rare they are. I'm told the Aprilia race ECU is a good option and won't hurt the warranty. Thanks for the vids and keep em coming.

[@MOTOPILOT6]

luvs2race370 Thanks for all the support, bud. Awesome that I inspired you to the brand. The Race ECU is the only method for maintaining warranty. As you already know

[@geegarcia3000]

Hello again MP! The bike is looking so sick with those wheels. And as for the tires you mentioned that you want to go back to the Pirelli, look into the Diablo Rosso Corsa 2. Maybe those tires might suit you better. I’m considering those for myself and riding style. As always stay safe out there and catch you on the next video.

[@MOTOPILOT6]

I'll for sure check them out. Been hearing good things.

[@geegarcia3000]

MOTO PILOT now I want to find myself those rims as well...🤔

[@jaysal883]

I think that happens to the best of us :) at least you didn’t side swipe a truck.

[@JimDiesel71]

Gotta say those Red Wheels look amazing with the Gold Chain and Sprocket. Makes me want to swap mine out on my RSV.

[@patrickcallahan2885]

Sounded like you had your radio on while you were in your truck, a little distraction. Dude, I’m so jealous! I can’t even find any aftermarket wheels for my bike. I’m with you, to me, handling is more important than down right horsepower. And less rotating mass improves handling. I love riding La Sierra and Cajalco and over the dam at Lake Matthews. Some of my favorite roads as well, and yeah, you over cooked it into that turn (scary)! But they really look nice and I’m sure they feel nice too!

[@julian-estrada]

Patrick Callahan im a Riverside rider too!

[@MOTOPILOT6]

Yeah, Im still a little rattled about blowing that corner. I recall now that I was distracted by the driver in one of those passing cars = late braking

[@aurorajones8481]

The wheels turn the bike into a magic carpet. I know because I have an 18 RF w/ the Mag's on. I thought about going to Carbons but the diff in weight from the Mags to the Carbons are not very much.

[@MOTOPILOT6]

Very true. As a matter of fact I saw a certain brand of carbons that was actually heavier than the forged.

[@silversurfertim2123]

Cool now your bike is even more badass 👌🏻

[@williamtravis9283]

Lucky there wasn't any oncoming traffic @ 5:33

[@massimobargagna5641]

Good thing no one was comming the other way brother be safe 1 he your at it again wow I would still ride but call it a day for spirited riding keep rolli h that power on

[@julian-estrada]

Notification squad where you at?

[@joshuamcgarvey2712]

i had a close call today on my bike and it wasnt my fault so i had to pull over and collect my self because i was shaking to much.

[@katsugi183]

Pretty significant saving on weight 💪💪👏📸

[@steve23464]

The 'Raymond Barone' of motovlogging. Anyone else hear this? Keep up the great content.

[@MOTOPILOT6]

Steve 23464 LOL. that's a first. The loud bike changes my voice in the mic. Check out the difference of my voice in my latest video about powder coated wheel costs

[@petersmernos8078]

Yes. Light weight is good. You should have bought the FACTORY Aprilia everything is lighter - standard. I like your videos Thumbs up.

[@charlieryan1736]

Glad you recovered from that fast bend👍🏻 looking forward to seeing the Dyno results. Thanks for another quality video

[@bchandy98]

charlie ryan where in the video? I must have missed it

[@charlieryan1736]

Brandon Chandy moto pilot said he will do a dyno comparison in his next video

[@deadpoolinmoval2088]

nice bro and still sounds amazing lol...

[@joshuamcgarvey2712]

very happy you didnt hit a car on that turn bro.... would have been a disaster for sure. great video though and great information.

[@fap9620]

my dream bike ! today i will sleep better xDD Keep up the good Work. where i live Coimbra-Portugal you can change (legal) that must mod´s you have in the rsv4. So , i just can watch xD

[@Untitled882]

Where are the dyno numbers?

[@dominicpascal]

Why didn't you get the RF?

[@MOTOPILOT6]

I didnt want to spend the extra $5k. I had not idea I would one day get the RF wheels.

[@fotislyk]

nice wheels!! i have the oz forged from rsv r 1000 in my 2004 tuono r!! the are much lighter!!

[@leadpaint1969]

How did I miss this video? Another great one MP!

[@pags1981]

You running M7RR's? Pirelli are great (have a RSV4 Rf with Diablo Corsa 2's). My favourites at the moment are the Dunlop D211 GP's on the ZX10R

[@SuperChiefer84]

My R1M has cast magnesium stock, haven't weighed them but I'm pretty sure they arent that light. Wish they were forged.

[@No_S3rvice]

M7's! I love those tires. I'm on my second set!

[@scottlincoln6286]

Sweet video braw - dude where you live is sweet, the desert is so badass...

[@theoriginalmungaman]

Actually forged aluminum is heavier than cast aluminum! The only reason these forged wheels are lighter is the design which can be minimal due to the increased strength.

[@fast4d1]

you probably have to reduce the comp and reb too

[@MOTOPILOT6]

fast4d1 I actually totally forgot to touch bases on the effects on the suspension

[@aurorajones8481]

I think id put a set of Carbons on my Daytona.

[@motogp3478]

Just curious you did all those upgrades for your RR, why did you not just go with a RF in the beginning ??

[@titangrv]

How do you clean anodized forged wheels ?

[@tedmarakas2626]

WD40. No harm to hard anodizing and leaves a fine film making next clean up easy.

[@flukemasterbrake2143]

Are these strong enought for pot holes

[@dixoncider7256]

good point.

[@davids2096]

It'd be nice if the bike came with all the stuff you wanted right off the bat I'm speculating everyone feels that way No one wants to spend money if they don't have to Later and have a good one

[@MOTOPILOT6]

I think some basic add-on's could help some buyers. But most of us want to choose our modifications that meet our taste and style. MP

[@chrisredfield3240]

Not everyone wants to pay for things they never asked for.

[@moto-]

when will u be done with the stunt show video

[@MOTOPILOT6]

hi JR....not sure when I'll fit that in. =-)

[@moto-]

K bro sounds good hope to see it soon

[@prajwalwane0009]

Which wheels are strong btw cast or forged aluminium. ..??

[@prajwalwane0009]

@Bad Example tqs for the reply buddy😊👍

[@tedmarakas2626]

Forged.

[@prajwalwane0009]

@@tedmarakas2626 tq u man.

[@DSOXBLADE]

You can't use two different dynos . Every dyno reads differently.

[@apollomorris9920]

Your bikes comes in 2020 6 different versions!

[@williammiller5654]

Are you running Metzler M7 RRs? In terms of feeling those differences I think some dont understand that it takes less energy to rotate the wheels (as you mentioned) makes me want to invest in lighter wheels for my CBR1000RR.. Btw.. Please check out my new channel and give a subscribe!

[@MOTOPILOT6]

Yes M7 RR. Some just don't get it. But sometimes we dislike what we can't obtain. I'll check you out.

[@williammiller5654]

MOTO PILOT couldn't have said it better.. and just for clarity.. I'm not running around spamming "sub for sub" lol. I've been tuned into your channel for a while and your content is always ON. Thanks bro!

[@probosusilo1251]

Motor impian dari kecil.tapi apa boleh buat saya orang miskin tidak mungkin bisa beli aprilia rsv4.buat makan sudah bersyukur 😭😭😭

[@tedmarakas2626]

Aren't you a bit too old for an RSV4 ? LOL

[@MOTOPILOT6]

Lol. I have the spirit of a 35 year old

[@tedmarakas2626]

@momo I'm a 35 year riding veteran. I do have a Tuono and an even faster Tuono. Ive got to say that a 200Hp bike can be terrifying at times. 10 years ago....I'd say....I need more power. Nowadays....I'd say....it has way too much. My reflexes are certainly not the same, taking a spill can be very bad at my age especially added to all my other injuries. When you go past the age of 50 and 60 these thoughts come to your head naturally, your thinking process changes. Of course, who doesn't want to be a kid again?

[@elduderinoakahisdudeness]

Probably should put 50 miles on new tires b4 going balls out.

[@weljo2001]

Waste Of Money....But Hey Its Your Bike Do What You Want....

[@joonya4427]

I call BS. The difference you feel is basically all in your head. There would be small differences, but you would have to be riding hard at the track to notice most of them. If the differences were as big as claimed, you would have to do more then adjust suspension, you would have to get it reworked, or put on factory suspension. Confirmation bias is a powerful thing that we humans are incredibly susceptible to it. But if your happier for having bought the wheels, then that's good.

[@Tenaciousdomi]

Unsprung Rotational mass is largely influential in acceleration and handling. I can't imagine how that doesn't make sense to someone lol all that momentum is insane. I've heard that for every pound you lose in unsprung mass, is equivalent to losing 9 pounds in total curb weight. That's INSANE.

[@MOTOPILOT6]

Joonya. You are 100% incorrect. Lessening the unsprung rotational mass is a huge difference that even a beginner would notice. It's like jumping off a heavy Harley onto a Sportbike as an extreme example. To ignore these facts means you've simply never experienced the change. Or you are closed minded. MP

[@joonya4427]

By the time you add in a tire and discs (front), and tire, disc, sprocket and sprocket holder, and chain (rear), the amount of reduction in the rotational mass is quite small. About 1.8kg on the rear. While physics says that this must make a difference to acceleration, I highly doubt that you could feel this anywhere except on the track when you are pushing at the limits of the bike. And on the front you have only saved about 600 grams. From Race Techs "Motorcycle Suspension Bible" p.106 - ".. the rider feels the percentage change, not the change itself." and "Studies have shown that the smallest change that most humans can feel is 10 percent." And this means in general, not just suspension changes. So, what does this mean? Acceleration - Your motor still has to push the total weight of the bike, which is now a whole 2.4kg (5.2lbs) lighter (which is stuff all). A stock RSV4 weighs 180kg (397lbs) (dry). So you have lightened your bike by a whole 1.3%. And that's before you add fluids and a rider. Once these are added, the total mass is more like 290kg (639lbs) (assuming a 75kg (165lbs) rider, plus a bit of gear), meaning you have reduced the mass by a whole 0.8%. If you think your bike feels better I'm happy for you, but don't fool yourself that you are actually feeling a noticeable difference in acceleration. Handling - If your front wheel (tire and discs included) originally weighed 6kg (13lbs) or less, then the change would be noticeable on handling. However, your new rims weigh 3kg (6.5lbs) by themselves. So, unless the tire and discs weigh about the same, or less then you are unlikely to feel the difference. Try removing your front wheel and weighing it. I would be genuinely interested in the results. I suspect you might be shocked at how little weight, as a percentage, you have saved, but if it is close to 10% then I will concede the point. Same applies for your back wheel. Tenaciousdomi - "I've heard that for every pound you lose in unsprung mass, is equivalent to losing 9 pounds in total curb weight." This sounds like total BS to me. Can you back this up with any research or data. It's easy for people to assert things like this, but when properly researched they often turn out to be false. MOTO PILOT - No, I'm not closed minded, but 28 years of experience have taught me that there is a lot of BS floating around regarding motorcycles. For example, you claim more power from lighter wheels. How is that possible? You put on lighter wheels and your engine gets more powerful. Wow, you bought magic rims. I suspect that you meant more acceleration, and as I have already shown, there is no way you can feel the difference in acceleration. Like I said, confirmation bias is a powerful thing.

[@joonya4427]

Yes it is physics. You haven't changed the weight of the part that is furthest from the axis of rotation, your tire. And because it is furthest from the axis, this will have the largest effect. I'm not saying there is no difference. I am saying that on the road, the difference is so small you would not be able to feel it. And unless you are a pretty good track rider, it's doubtful you would even feel the difference on the track. Any perceived difference is therefore in your head. But if changing wheels makes you happier on your bike, that's good. After all, we ride bikes for the way they make us feel.

[@joonya4427]

Yeah I agree with you. I just don't like how he made out there was a huge difference when in reality there would be no practical difference at road speed. Young / new riders might be fooled into spending a lot of money on an upgrade that is of little to no benefit unless riding hard at the track. They would be much better off throwing money at suspension upgrades, for example. Also, there has been a talk of rotational mass effecting acceleration. The reality is that the total mass of the vehicle is by far the biggest factor that governs acceleration. Power to weight governs how quickly you can accelerate the vehicle, and therefore how quickly you can accelerate the rear wheel (assuming no loss of traction), not the other way round. And he has reduced the real world mass of his bike by less than 1%. There is no way that makes a noticeable difference on acceleration. As to handling, I have said I would be interested in knowing, as a percentage, how much of the total rotational mass he has removed. If it is a decent percentage, then maybe he can feel a difference, but with only 600g on the front, for example, I doubt it. And as I already said, he hasn't changed the mass of the part furthest from the rotational axis, the tires. So, I reckon the difference is he feels is mainly in his head. But if he is happier with his bike, then that's OK. I just don't want others to think that this upgrade makes the difference he claims it does.
