Thanks for the reply, It's taken a while to msg back. Is it worth trying? i will probably have to order 10 sprockets of both front and rear to try this out for myself, guessing the idea maynot have taken off commercial wise.
Has anybody ever tried the 428 chain and sprockets kit as sold by T3 racing on the yamaha r6, 2007 onwards? Interested to know the effects of improved acceleration etc. If so, is there a tangible, noticeable difference? Thanks
