Ok, everybody else on here seems to know exactly what it is, but I have no idea...
What exactly is a cush drive?
I've heard everyone talk about it, and I know I have it on my wire wheels, but I'm clueless as to what it really is or what it does.
I will probably need to know this before I start to put my wire wheels on my bike.
Thanks guys

Hey man... there is no bigger idiot on this site than me pal!  The cush drive is on the sprocket side of the rear wheel. Inside the hub are six (I think) large rubber dampers that fit down inside the hub. Then the plate that the sprocket is bolted to fits over/into this area of the hub. It provides some damping for the primary drive I reckon. I didn't think much of it on the SR, until I took the wheels off my '03 Suzuki SV650 to get some new tires put on and it has a cush drive as well... guess the technology is solid... ;D |

Thanks Gary! So "cush" must stand for "cushion"? Or something.
Good to know!

Hi,
Yes pretty well...it dampens out the shock transmitted by the chain drive and transmission to both ends of the run...they've been on at least Japanese bikes for as long as I've owned them...err...so that'd be a little while...heh, heh...
SR ;D

I'd say it helps with the stress that would be generated it that area with taking off changing up/down . If you chain was a bit dodgy (tight and loose) it would help with the strain on the main drive shaft too as it would have a bit of give . They still put them in new bikes so they must do something important anyway. Hey & whats wrong with being an idiot it is an exclusive club you know ( I'm the freakin captain) , cheers from Dave.

Also helps with stress on the teeth of the tranny and primary drive gears. Some bikes (XS650 is one) have a similar function in their clutch hub - that's why the XS doesn't have one in the rear wheel.
