I had fitment issues

Comments On Mar 16, 2014:Comments On Mar 16, 2014: Only reason it's not a 5 is I had to order a 48t rear sprocket to make it work. I ordered the kit and with 14-50 the chain was too tight not allowing the guide to have the bottom bolt. I emailed RM and they sent me a longer chain no questions asked. This caused it to be too loose at the end of adjustment. I then ordered a 48t rear and the original chain works good. So if ordering the kit......get a 48t rear.

So Far So good

Comments On Mar 28, 2011:Only have one ride on the new sprokets and chain, however have not had to adjust it whatsoever. Compared to a stock OEM chain where it requires two adjusments on its first ride, seems to be a better product for a good price.
