Cush drive rubbers

Hello a newby here so apologies if (a) I'm posting this in the wrong place OR (b) it's already been posted debated and discussed.  So, I have a 2000 model which has had a sprocket and chain kit fitted (DID) but still the transmission feels bit a rough.  I thought I might change the rear cush drive rubbers so looked for the OEM parts and found them to be an eye watering £60 for a set.  There are other after market parts for less than half the cost.  Does anyone have a view about which is the best way to go with this?

Hi, welcome to the site.

Sorry I don't have a suggestion which is the better way to go. I'm also not aware that it's an item which has been discussed much nor replaced. Maybe you could find them 2nd hand.

Maybe post up the problem you are experiencing with the rough transmission and someone might be able to assist, the problem could be elsewhere.

Hi there.
What's the mileage of your steed?
Not heard of the drive rubbers being a problem but I know they wear easily on big single cylinder engine's. Best way is to take the back wheel off and look for perished rubber and see if the sprocket carrier all tally up nicely before you start splashing the cash. How's the chain slack?
