well here it is, the rear rim is off a yamaha fzr its an 18 w a milled down cush drive and rotor size of the rim.. n the front i made a plate and flipped the rotor on an f4i wheel

what do you guys think?





ps its for sale, its freshly rebuilt, valves are shimmed perfect, starts first kick everytime.
comes w dirt wheels and is easily converted back

I'm new to supermoto bikes, I was just wondering what the cush drive was...:hmmm:, I got a yz426f I plan to convert to supermoto and I'm planning on using mags from an fzr.

cush drive is in the hub of the rear wheel, the sprocket instead of connecting directly to the hub is on a carrier and inserts into the rear hub. There is a rubber damper piece that fits between the two and helps CUSHion the drive train and absorb some of the force that otherwise would be transmitted to your gearbox.

its an easy swap, just take a half inch out of the hub (cush) and a half inch off the rotor bolt surface, make some spacers for your axles n thats it! oh and machine the inside of the cush to sink the outside bearing in... the front i didnt use an fzr...

Thanks a lot, so what kind of wheel did you use for the front? Now that you mention it it does look a bit different than your rear wheel.

Nice bike. I'm pretty sure that is an early f4 wheel. The f3 is a five spoke.
I've never thought about the handling effects of using an 18 rear and a 17 front. Quicker steering?

Seems to be pretty flicky, but its stable, i imagine the height of the rim is offset by the fact that my tire isnt as tall...its only maybe a half inch taller than the 17 i had on my f4i with a 180 on the back, its got a 140 18 on it now...

heres how it looks currently by the way
