The rubbers are a very loose fit for from day 1.

From past experience the assembly should be a snug fit whan you put it all together.

Often I've had to employ Mr Rubber Mallet to knock the carrier back into the hub on other bikes.

Rubbers are too small= lots of movement=rapid wear.

Sorry, didn't pay much attention to it so don't remember. :smoke:
Noticed that too, when I removed the rear wheel first time the carrier and rubbers just fell off. Gonna talk to the techs about it when I'm in for the 20kkm service.

hi has anyone got a number to ring so i can get some of these cush drives. im on the wirral so anywere local to that would help.
and i have to agree it is pritty naf that they need replacing so quickly!!

thanks Tompe

Maybe a polyurethane replacement would help? for those who don't know polyurethane is hellish tough and available in a range of different grades of hardness. that way it would retain the cush, could be manufactured to be a more snug fit and last longer. :)

I had the rear end jacked up today to oil the chain and noticed a lot of play in the direction of rotation between hub and carrier while spinning the wheel. Also side to side play is very noticeable on the carrier...........this is more serious than I thought and hope the carrier bearing isn't knackered like Timpo's,that amount of play ain't healthy :(

I'll take a closer look tomorrow at the bearing and I will speak to the dealer afterwards.

Aaahh just done a search and found this

Bleh, cush drive was fine when I stored it for winter, now I've driven the bike 500km this season and noticed a lot of yank in the drive train. Feels like all the cushions fell out all of a sudden hehe. Anyway, is it dangerous driving around like this? The tech said it could be fixed on the guarantee but he didn't have time until 5th of May.

Not an expert, but did notice on my old Tenere that a small amount of grease had squeezed through onto one corner of one of the cush rubbers after greasing the axial shaft. The rubber had turned to cheese in that one spot. IMO, its not a good idea to lube the cush drives, they need to be clean and dry. I have done over 10,000km on my current cush drives and they seem to have a lot of life left.
Just wondering if the salt on the roads in the UK over the winter has had any affect on them? (If in fact they do salt the roads)
What is the white stuff on the rubbers in the photo?

Tyre wear mainly... I have a non cush-drive hub on my XR650R, and it certainly wears it's tyres more quickly (also has a touch more power of course x). Basically every power pulse, together with the take up and engine braking is directly transmitted to the tyre, and on soft knobblies particularly, will wear more quickly. You might also see a little more wear on the sprocket teeth for similar reasons.

That said, I got 4000 miles out of a Dunlop 908RR on the XR last summer, which is about what you can expect from a TKC on the Tenere, and with no cush drive to wear out and knacker your chain/sprockets, you might actually end up saving money?!

An 18" non-cush rear wheel conversion is something I'm going to look into now I'm back in the UK Timpo - watch this space as they say...
