The stock rear sprocket size on the Honda Grom is 38 teeth. You can go up to increase your acceleration at the expense of top-end speed. If you go down, you can get a higher top-end speed at the expense of acceleration. A few rules of thumb with 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
