I am struggling to find the S1000RR listed to buy a Supersprox rear sprocket. My usual buying choices of Sportsbikes and DemonTweeks are unable to help as there filters are incorrect and when you type in your bike model nothing comes up, which they admit is an error. However i cannot order as they can't tell me which will fit. Secondly as i have the forged wheels on a 2015 S1000RR Sport will the sprocket differ from a normal wheel. There are plenty on eBay with 45T but i don't know if they will fit the BMW. Anyone else using these on there S1K with forged wheels. If no luck i will buy Renthal, i just simply prefer the look and increased longevity of the Superspox.
