Recommended Gearing Questions come up regularly about recommended sprocket changes and the required chain lengths for superbikes. Here's my recommendations for general street and track use. There's a "sweet spot" - around 4,600 RPM @120Km/hr in 6th gear for liter displacement superbikes, a little higher for 74X's. Obviously, faster tracks will require rear sprockets with fewer teeth, slower tracks more teeth (and possibly longer chains.) I strongly recommended NOT changing the stock front sprocket or chain size for safety reasons. Just my opinion. |
Brilliant, thanks !.mav |
Stunning :D:D:D:D |
Cheers! Shame I need a new chain for my 749S to try it though :( |

Great stuff (once again) Shazaam! I changed the gearing on my 996S to 14/40 and was amazed at the way it makes town riding so much better, but I was wondering why you think it's dangerous to change the front sprocket size? |

3rd line down on the chart (14/40). It'll improve acceleration / drive for one thing. |

I was told that due to the torque of the bigger engine, and the increased chain size, the chain did not appreciate running round a smaller radius sprocket, and that it was better (allthough more expensive) to go for a larger rear sprocket. I'm running 15/40. |
