Meh, this will have been discussed a million times already but ive just swapped my 17t with a 16t on the advice of this very forum. I am extremely happy with the results, If you havent done this already and want crazy acceleration, do it!
Bowed to the wisdom of those that know and swapped for the 15/42 gearing. Wow, less jerky at small throttle openings, easier pulling away but the pick up is fantastic. Blatting along between the bends where previously I was hitting 60 before throwing out the anchors, I'm now hitting 80...
