Hi, I’ve just bought a imola kit, and I was thinking about saving up for a af 5 speed gearbox.Would it be worth buying,or stick to li50 gearbox.cheers Simon

genral rule is your final drive ratio is dictated by your choice of pipe, that been said im just building one of these with an af close ratio 4 speed box and im going for a 5.1/1 ratio to make sure it can rev enough, its getting a 60mm crank so I can lower the port timings a bit to get a more rideable engine, often the port timings are very high on imolas and make for a very peaky engine which can be not much fun to ride, ive got a pm pipe which is a revvy pipe. I know they do a short 5th gear version of the af 5 speed which will probably go well with an imola as long as you get your sprocket choice right.

As Holty has said, gear requirement will go hand in hand with pipe choice... and pipe choice will need to go hand in hand with how you like to ride / what you intend to use it for. Without more details it is very hard to give you any advice that would be worth listening to. An Imola with a revvy pipe will require different gearing to the same motor fitted with a low revving expansion, and same goes for low revving or high revving clubman.
