AFAM aluminium rear sprocket 520 pitch for YAMAHA YZ 125, YZ 250, FANTIC XE 125, XEF 250 and RIEJU MARATHON 250 1999-20 - 13323+

AFAM offers this rear sprocket for YAMAHA WRF 250, YZ 125, YZ 250, YZF 250, YZF 450, FANTIC XE 125, XEF 250, XEF 450, XX 125, XX 250 and RIEJU MARATHON 250 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.

Specifications and fitting tips

• Color: Aluminum
• Chain pitch: 520
• Material: Aluminium
• Rear sprocket version: Self-cleaning
• Type: Rear sprocket
• Mud-grooved aluminium rear-sprocket

Choose the number of teeth from the list: fewer teeth on the front sprocket (or more on the rear) gives more acceleration, the opposite gives a longer gearing.

Cross-Mania tip: Replace the rear sprocket, front sprocket and chain together, tighten the sprocket bolts in a cross pattern with threadlocker and set the chain slack to the manual.
