How fast is the RS660? Tuned Aprilia Supertwin on the Dyno, and getting ready to race.

The fast RS660 may be running, but it needs some time on the dyno to get it running perfectly. But how much faster is it than a stock bike?
And then the final touches need finishing, so he Aprilia can go home.

Thanks to Black and White bikes for the custom Dyno mapping

I love this channel. So important for anyone that has an aprilia.

These videos are awesome. I have had my 660 since 23 but in the process of converting to a full track bike this winter. Timing of these have been perfect for me 👍🏼n

Great work, best wishes racing next year.

[PhuManchew]

Good timing, I've been thinking about getting this bike. Where I live, more than 120 HP is not going to be used very often.

[mikefandango]

A real insight into claims of new bike manufacturers and actual facts of HP? Once again Dave putting into layman’s terms for us real world public!

[laurapeters]

Looks ace Dave 👍🏻 hope Rob got an extra chocolate for working in the cold 😂

[Matt-wesi]

really awesome stuff, would love to see you build a CB 500 race bike, they are super fun like you wouldnt believe

[ManxAndy]

Good evening Dave…..Obssesion bobble Hat is keeping me well warm….I’m tempted for the Hoodie next….Merry Christmas 👍🇮🇲😉

[linuxpyle]

I can't speak to how it goes but it absolutely sounds the business!!!!

[badtsersc]

Hey absolutely love these videos, run my own rs660 aswell. Is it possible to get a full parts list at some point? Especially the rear brake setup is something I would love to copy myself

[chrisdunham]

I got 156mph out of mine running Gabro UpMap, Gabro stacks, Sprint P08, Akrapovic exhaust and a splash of octane booster.

[RumblestripDotNet]

So roughly 110-112 hp at the crank for your bike. 10-12% drivetrain loss equaling the 99 rear wheel registered on the dyno.
