The gear ratios in geared mopeds are very important to make the most of the engine. A gear ratio that is too long may prevent you from using all the engine’s power, and one that is too short can have the same effect. Normally, you should follow certain guidelines to choose them.

If you choose a front sprocket with fewer teeth, you will achieve more acceleration, but a lower top speed. If you choose a larger front sprocket, you will lose acceleration but gain top speed.

Choose from:

• 11 teeth
• 12 teeth
• 13 teeth
• 14 teeth
• 15 teeth
• 16 teeth

Sprockets with 4 holes to avoid issues with the locking plate.

Distance between bolts:

• M5 - 25mm
