bit late i know, but I've just done this to my 916, £140 from moto rapido, hardest bit was removing the circlip, does look nice, and keeps the cost of replacing the sprocket to a nice level aswell.....:roll:

i'll second that removing the rear circlip was the hardest thing to do

Ordered my carrier from B and C express £105 and that included vat, I will fit the carrier and new sprockets over the christmas break, how did you get the clip off ??

sheer persevarance in my case,it was a really tight fit but i was changing from a stm one to a renthal and needed it off as i was doing a trackday 2 days later. be careful when tightening it up as the metal bolts on the carriers arent very strong and can snap easily

Thanks for your advise.....:D
