RACETECH OE style Chain Guide - Red for HONDA CRF 250, CRF 450 2007-2026

The RACETECH R-CRUCRRS0007 chain guide is designed for HONDA CRF 250, CRF 450 from 2007 to 2026. 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 number: R-CRUCRRS0007
• EAN code: 8033378974712
• Engine: 4-stroke

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?
