RENTHAL aluminium rear sprocket 520 pitch for YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250 and FANTIC XE 125, XX 125

RENTHAL offers this rear sprocket for YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250 and FANTIC XE 125, XX 125 1999-2027. 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.
