11-Tooth Sprocket Aprilia RS/RXSX/RS4 Derbi GPR, Senda R/SM/DRD 06-14 JT Sprockets

Front sprocket of quality from manufacturer Jt Sprockets for Aprilia and DERBI engines. Choose the number of teeth you need.

Attention: Check carefully the type of splines on the sprocket with the sprocket lock before ordering, to ensure it matches the one in the photograph.

The gear ratios in geared mopeds are extremely important to get the most out of the engine. A ratio that is too long may prevent you from taking full advantage of the engine's power, and one that is too short can have the same effect. Normally, you should follow certain guidelines to choose them. 
To understand this: if you use fewer teeth it results in a shorter gearing (higher RPM), whereas if it has more teeth it lengthens it (higher top speed)
