Typically how much play in cushion drive on rear sprocket? Mine moves close to 1/4 inch back n forth. Noticed it today on 280km ride.

On a new cush drive the play is zero.

The replacement point is when it becomes overly annoying.

I replaced my "cushion drive" at 23,000 miles because I thought that the play was excessive. Your play seems excessive to me.

This bike just hit 10,000 km or 6200 miles.

Well, that sounds premature for replacing the cushion drive.

How far from the center are you measuring the 1/4" of slop?

Jason

P.S. As a reference point, the service limit for the cushion drive on my road toilet is 0.40". That figure is the total distance that the wheel can move as measured 6" from the center.

 

[Steve.k]

I never actually measured it was just stopped on road checking things out when I moved sprocket by hand. I’ll get a measurement today. Looked like about 1/4. The other bikes there had none. Vstrom 650,ktm790.

 

[Steve.k]

It’s moving in same direction as chain would run. Backn forth. No side play.

 

[Steve.k]

Guys went out and rechecked this morning. Its about 1/4 inch total movement back n forth. Not that bad. However there is side play which might indicate bad bearings. Great white North said to check that. It maybe that outer bearing. I’ll get it pulled down. Thanks everyone.

 

[Steve.k]

Well pulled all apart. All
Bearings good. Just some wear in drive. Maybe most are like that. I’ll order new cushion and put in.

I'll suggest one could save some money & purchase a higher quality OLDER used Rubber cushion from ebay or salvage yards.
I believe that my 87 is still using the original 87 part. This style cushion goes clear back to 1983 KE175-D series bikes.
I think that 2006 & up Thailand production KLR's is when the rubber compound changed.
Still the same part number apparently, which is UNUSUAL. #92075-1068

Use an older year model & the part number in searches, but don't purchase New part.

 

[Steve.k]

I’ll check into it. Thanks. I have about 600km on big bore now maybe it’s stretching it abit. Quite abit healthier.

Yeah, besides mileage, it's also the ham-fisted accel/decel cycles by the operator. Such behavior also wears out tires and drive chain/sprockets faster, from what I've read.

 

[Steve.k]

I also tried the 16 tooth front sprocket but for mostly gravel and off road i found it to much of a jump. I may try a 42 rear or the 16/44 combo gives a 2.75 ratio which maybe better.

I replaced my sprocket, chain and cush drive on my Gen 1 at the same time, it had been feeling rough at constant throttle speeds (highway and anywhere that I had a steady RPM). I changed all just because the chain and sprockets were due and it was a completely new ride afterwards-but it was probably mainly the chain at that point.

 

[Reveille]

Old thread revival.
Have any of you tried the cush replacement Procycle sells?

 

[Klrian]

Does no one else just shim the cush drive. I cut pieces from a plastic jug slip them between the cushion and the hub, install the sprocket carrier and check for play.

 

[Tom Schmitz]

Yes, many do that.

That doesn't help me in my quest to bust the KLR Owner stereotype by spending a ton of money on my bike..... 🤣

J/K but yeah, I couldn't be bothered trying to bandaid it over $25 every 10,000 to 20,000 miles...

Ya I actually did that this spring with 63,000 km on bike. Used pieces cut from an old inner tube. Only did it because the actual part was a week away. Now have a new replacement waiting for the next time the wheel is off.

If the cush drive only lasted 10,000 miles I'd have used 4 last year, 38 in the last 13 years. I replaced one crush drive at about 40k miles, since then I have just shimmed them. If you only ride 10,000 or 20,000 miles a year then maybe just replacing them makes sense to you.
