Cush Drive

[POSR]

Would someone please explain the mechanics of the cush drive?

The wheel holds slotted rubber blocks. The hub has tabs that go into the slots in the rubber blocks. This provides a cushion between the wheel and the drive train.

these rubber pieces

fit in your rear wheel housing behind the sproket

The sprocket goes over top of the area and slides into the rubber pieces (cush rubbers)

[heavybusa]

once together the cush rubbers "cushion" the torque from the chain to the rear wheel making for smoother shifts and take offs.

Without them your starts would or could be very abrupt ! Like metal to metal with no slack to allow for give. And like he said, it smooooooths things out for you ! Well it for sure does for me

And there you have it
















Another perfect job by the members of Hayabusa.oRg

Nice job

The cush rubbers are there so when you get a little slop in em, the wheel hub falls off every time you pull the rear wheel.

Suzuki designed them to help build character in less mature riders.

Nice explanation. Thanks! So how do you know if they wear out? A visual inspection looking for cracks? It doesn't really look like they deteriorate.

Look at the picture in post 4. There are two sets of Cush rubbers there.

The top ones are brand new - the bottom ones are worn out - notice the marks in them?

What's the recomended interval for changing them? Is there a recomended mileage? I think I changed mine out somewhere around 20,000 miles.

[COLDSTONE1298]

changed mine out a few weeks ago at 27,000 miles

Busa Bill......GOOD ONE..."character building".........works for me.

As far as replacement. *You'll start noticing a bit *of a pause/gap (very small) between acceleration torque, and downshift drag (engine braking). *Almost feels like chain slop. *It's so minute, that you might miss it for some time. *I was noticing I've got about an 1/8"-1/4" of free rotation between the rear wheel fore and aft grab (link engagement). *Did this on a rear stand by the way.

"I believe it's time". *

Get your rear end in the air, roll your wheel back and forth, forward, then gently backward. If all you get is tension from the chain, you're good. *If you have failing cush rubbers, there will be an independent shift between the rear sprocket hub, and the wheel center. *Like the chain and sprocket aren't moving, but you can still get the tire to roll a wee bit. *With as many foot pounds of torque as even a stock "un-modded" Hayabusa puts out, they get mashed, start to compress, and eventually fail. *Although they won't fall out on you while you're driving. *In this case, "Snug is good". *

By the way "Heavy"...NICE PICS !!!!

thank you wise 'Busa scholars.....I feel much more Zen now about knowing what a cush drive is.

[P-Willy]

I wouldn't know a damn thing if it wasn't for this site!

[babuski]

So after 44,000 miles....should they be replaced? I am doing some work over the winter and have the money.....btw...how much are a new set of these cush components....?

[BowDown]

Nice writeup. I was wondering what the hell a cush drive was.

I just replaced mine wednesday @ 49.9k. after taxes the set o' 6 cost barely under 50 bucks at the local stealership. difference is day and night! a lot smoother now. had to soap the new ones to get the hub on. listed on the ipb # 17 - shock asorbers ,on the rear wheel screen.
