Now that we know what a "cush drive" is...

...what is its purpose :?:

If it works the way I think it does, it transfers the energy from the chain-driven sprocket to the wheel via the rubber cushion thingy's. Is that right? :?

I guess I had always assumed the rear sprocket was bolted directly to the wheel hub. Is the purpose of the cush drive to dampen some immense, damaging physical force?

Just curious,

Martin

Pretty much. It minimizes shock and vibration transference to and from the rear wheel at the expense of a bit of driveline lash.

Pat- 2007 DL650A was ridden to all 48 contiguous states. I didn't quite make it to 17,000 miles on the 2012 DL650A.

the damage would be to the engine from being too directly in contact with the pavement, nothing to cushion transitional driveline lash. dirtbikes generally don't have them, unless they're meant to spend some time on the pavement.

edit- too slow.

I had to go look this up in my newly arrived V-strom service manual (gotta love Onieda Suzuki's quick shipments!). Is this something mounted on the rear wheel hub assembly? All I could find in the exploded diagram (chassis section, page 6-33) is a little half-moon looking thingy called a "damper". Looks to be about the size of a pack of cigarettes. Is that what is causing Stromette all her woe?

That's it. There are 5 of them in the hub of the wee or the vee.

The only time I've ever destroyed these pads is when I didn't torque the axle nut properly.

And it didn't take very long to kill it ....

I measured the dampers I removed from Stromette's Strom & compared the measurements to the used replacements I had obtained. I could not find a reliable place on the damper to compare measurements

I do know that the replacements removed just about all the free play she had & the small aluminum shims I inserted made the hub a nice snug kit.

Hopefully this will last her a good while & remove the stress from her journeyings

For the technically minded, IMO the elastomer ratio to carbon black was off in this batch of dampers. Infrared & nuclear magnetic resonance spectroscopy showed this.

Joke, Joke. Stromette said I had to write an explanation of why hers failed

Yes, there is a lot written on another forum about the first couple of years of Stroms that had the rear wheel (yes, the whole thing) was about 2 millimeters off (to the left, I believe) becasue of a design flaw in the bushings. This made the chain off center between sprockets, and as a result - besides a terrible premature wear to the drive line - also completely distroyed the cushions as well. An outift in Germany makes a slick repalacement bushing that property recentered things for the Stroms that had this problem. The point was, it's not just the chain/sprockets that suffered, but also the cushes. Something to consider the next time you change out your chain and sprockets... check those cushes. Worn cushes can and will make all sorts of funny vibrations and harmonics, espeically at speed.

Not just early models but every 1000 ever made have the alignment problem.

For real? I thought I heard or read somewhere that they fixed it. If not, then WTF???! Why can't they get this right after so long? So... have you gotten the right bushing? If so, did you get the German one? Please expound.
