The large toothed wheel bolted to the rear wheel: the chain meshes with it to drive the bike forward.

Available in several colours.

RFX offers this rear sprocket for GAS GAS TXT 250, TXT 250 GP, TXT 280, TXT 300, TXT 300 GP, BETA EVO 125, EVO 300, EVO 300 2T SS, REV3 250, REV3 270 and SHERCO ST 125, ST 250, ST 300 2000-2023. The rear sprocket receives the engine’s power through the chain and turns the rear wheel. Its number of teeth sets the gearing: with more teeth the bike accelerates harder but has a lower top speed; with fewer teeth it is the other way round.

Why fit a new rear sprocket?

The benefits:

New teeth that hold the chain properly and make it last.
The number of teeth is chosen to suit the terrain: more teeth for slow, tight sections, fewer for fast tracks.
Aluminium or steel: aluminium is lighter, steel lasts much longer; “mud-release” models have cut-outs that clear the dirt.

When should you replace the rear sprocket?

Pointed, hooked or uneven teeth, or a chain that lifts easily off the back of the sprocket: the chain kit needs replacing.
