RACETECH OE style Chain Guide for HONDA CR 125, CR 250, CR 500, CRF 250, CRF 450 1999-2004

The RACETECH chain guide is designed for HONDA CR 125, CR 250, CR 500, CRF 250, CRF 450 from 1999 to 2004. The chain guide, mounted under the swingarm in front of the rear sprocket, keeps the chain properly lined up. It stops the chain from coming off when the suspension is working or when a rock or a rut knocks it sideways: without it, the chain can jam and lock the wheel.

Specifications

• Brand: RACETECH
• Manufacturer part numbers: R-CRUCRNR0003, R-CRUCRRS0003
• Available versions: Black: ref. R-CRUCRNR0003; Red: ref. R-CRUCRRS0003

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.

Why RACETECH?

The brand has supplied the plastics for Mitch Payton's Pro Circuit Kawasaki team, one of the most successful teams in AMA Supercross, as well as for the Beta Offroad Factory team. Its Worx chain guide is a one-piece design fitted with a removable, self-lubricating TPU internal wear pad.
