Shock absorber wear: signs you can spot in the garage

Shock wear creeps in slowly, and you get used to vague handling. Yet grip and braking distance depend on it. November is a good time to check: the bike is parked and you have time.

• Wipe the stanchions and seals with a clean rag, then look at them under good light. Oil streaks on the tube or body mean a leaking seal.
• Inspect the stanchion surface: rust, scratches and pitting will eventually cut the seal.
• Hold the front brake, push the forks down and release. They should rise smoothly, without springy bouncing or knocking.
• Do the same at the rear by pressing on the seat or rack. More than one or two bounces after release calls for a proper diagnosis.
• Grab the lower fork leg or the swingarm and rock it sideways: play or a knock points to worn bushings or bearings.
• Servicing forks and the rear shock is workshop work: there is pressurised oil, loaded springs, and a mistake shows up under braking.
