Some sort of floating hub maybe???

[notme]

Anyone got any idea on this? While giving the Kwaka's chain a good clean and lube i noticed that the rear sprocket assembly seems to move a few mm in relation to the wheel hub itself....the photo's explain it better! No problems noticed while riding, and there don't seem to be any bolts that go all the way thru the whole assembly, so is this some sort of floating hub as in floating discs? Is it a problem? Can another Kwaka rider see if they have the same thing?

My old Honda use to have a similar thing with wee rubber "cushions" between the two, I guess it was to take up the shock of on/off throttle movement?

Most sprockets aren't bolted rigidly to the wheel, but have cush rubbers around the mounts, to absorb some shock and make gearchanges smoother. As the bike gets old, these will get more and more play as the rubber blocks in the cush drive get irreversibly compressed.

Ah ok cool.

reckon it's worth looking at replacing these rubber thingummies? Or not until i notice a problem?

Glad to know it's "normal" though - cheers guys. It never ceases to amaze me that you can post a question on these forums and get a reply 5 mins later

If you're getting problems with your gearchanges with the chain properly adjusted and lubed, and/or you notice quite a bit of 'slop' when you throttle on/off, and/or when you put the bike in gear with the engine off, roll it back and forward with the rear brake on and theres a lot of movement in the sprocket, then change the cush rubbers.
Note that they're often ridiculously expensive for what they are, and you can extend their lifetime somewhat by getting some flat strip rubber and packing them out with that.

same as what everyone else said. If you take your back wheel off, you'll see the rubber cusions behind the sproket/hub. Just takes the edge off your bad shifting

Who told you about my sloppy shifting???

Are you one of the instigators of the "Clutchless Shifting" thread

Thought you might have been Japanese but it would have been "Who tord you-o abotu my shroppy shifting" if you were!

Sloppy typing fixed now, sloppy shifting still a problem but I'm working on it.

Just have to fix my sloppy drinking now....
