INNTECK Chain Guide for YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250, YZF 450 2003-2008

On YAMAHA WRF 250, WRF 450, YZ 125, YZ 250, YZF 250, YZF 450 from 2003 to 2008, the INNTECK chain guide fits in place of the original part. Sitting just in front of the rear sprocket, the chain guide channels the lower run of the chain. Off-road, it's a safety part: it keeps the chain from derailing and protects the sprocket from impacts.

Specifications

• Brand: INNTECK
• Manufacturer part numbers: CG6003, CG6003BL
• Available versions: Black: ref. CG6003; Blue: ref. CG6003BL

Choosing the colour

All versions fit the same way: the colour is purely a styling choice, to match the bike or to stand out from it.

When to replace it?

• Wear pad grooved by the chain, almost worn through or cracked.
• Guide bent or broken after an impact.
• Chain rubbing on the side plates instead of running through the centre.

Check it every time you wash the bike: a pad worn down to the metal wears the chain, and a bent guide can throw the chain off.

Fitting tips

1. Remove the old guide and clean the mounting points on the swingarm.
2. Offer up the new guide and check that the chain runs through the centre without touching the side plates.
3. Tighten the bolts to the manufacturer's torque, with medium-strength threadlocker.
4. Spin the wheel to check the alignment, then set the chain tension.
