Rear sprocket Derbi Senda SM DRD /GPR Nude / Aprilia RS4 420 CNC Aluminum VOCA

Rear sprocket made from aluminium alloy by VOCA for Derbi Senda SM / DRD/ GPR Nude or Aprilia RS4 with a 420 pitch.

Latest generation rear sprocket from VOCA Racing, specifically designed for Derbi Senda SM / DRD/ GPR Nude or Aprilia RS4, with a 420 chain pitch. Manufactured through a precision machining process from aerospace-grade aluminium alloy (AA-7075-T6), this rear sprocket redefines performance and durability standards in the motorcycle components sector. The choice of this advanced material not only ensures strength comparable to traditional steel sprockets, but also offers a significant reduction in overall weight, thus contributing to a notable improvement in drivetrain efficiency and motorcycle handling.

The monoblock structure of the VOCA rear sprocket, with no joints or welds, ensures superior structural integrity, optimising power transfer from the engine to the rear wheel with minimal energy loss. The variety of colour finishes allows for visual customisation, aligned with the rider’s aesthetic preferences and the motorcycle’s colour scheme, without compromising the functional integrity of the component.
