Rear sprocket Sherco SR-R / SM-R 50 E5 transmission sprocket, 428 pitch, 5 bolts, alloy wheel

Rear sprocket for Sherco SR-R / SM-R 50 E5, 428 pitch, 5-bolt mounting for alloy wheel.

The transmission rear sprocket determines how the motorcycle responds when opening the throttle. A worn rear sprocket, with sharp or hook-shaped teeth, causes the chain not to mesh properly, resulting in jerking, transmission noise, and rapid wear of the front sprocket and chain.

This 428-pitch rear sprocket allows you to renew the rear transmission while retaining the specific mounting for an alloy wheel, with 5-bolt fastening and a Ø110 mm diameter. It is a key part when replacing the final drive kit or adjusting the motorcycle’s gearing.

Available in 50 teeth and 53 teeth. The 53-tooth version shortens the gearing, providing better take-off and improved acceleration response. The 50-tooth version leaves the gearing slightly taller, useful if the goal is for the engine to run at lower revs at the same speed, always depending on the installed front sprocket and engine configuration.

The black finish matches the aesthetics of Sherco Enduro and Supermotard models very well, giving the transmission a more refined visual appearance compared to an old, rusted, or marked rear sprocket.
