Front sprocket from the manufacturer Allpro for all Derbi Euro 2-3-4 engines with 420 chain pitch in neochrome titanium colour.

The gear ratios in geared mopeds are very important to get the most out of the engine. A gear ratio that is too long may prevent you from making full use of the engine's power, and with one that is too short, the same can happen. Normally, you should follow certain guidelines to choose them.

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

Number of teeth:

• 13
• 14
• 15
