A few rules regarding gear ratios for sprockets are as follows:

•    Drop teeth on front/add teeth to rear = increased torque, increased acceleration, wheelies, racetracks with short straights
•    Add tooth on front/reduce teeth on rear = increased top-end speed, open road cruising, lowers RPMs, better gas mileage, tracks with long straights
•    1 down on the front is like adding 3 teeth on the rear
•    The bigger the rear sprocket, the lower the gearing and the faster the acceleration
