AFAM aluminium rear sprocket 520 pitch for BETA EVO 125, EVO 200, EVO 250, GAS GAS TXT 250, TXT 280, TXT 300 and SHERCO ST 125

AFAM offers this rear sprocket for BETA EVO 125, EVO 200, EVO 250, EVO 300, REV3 250, GAS GAS TXT 125, TXT 250, TXT 280, TXT 300, TXT 300 GP and SHERCO ST 125 2002-2023. 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.

Specifications and fitting tips

• Chain pitch: 520
• Material: Aluminium
• Rear sprocket version: Standard
• Type: Rear sprocket
• Racing aluminium crown gear
• Ultra-light with hard anodization

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.
