Motorcycle Suspension Mid-Speed Valve Springs

MSV / Refill Springs

All rebuildable suspensions need basic shared parts — locknuts to hold damping pistons to base towers, teflon lined shaft collars or acetal rod bushes to keep sliding tubes concentric with low friction, tiny Mid-Speed Valve (refill or non-return) springs to tune shim stacks and rubber o-rings to seal oil and gas. Motorbike front forks and rear shock absorbers both require these parts for servicing and valving tuning; this category collects those essentials.

How MSV and refill springs help valving

  • Keep sections of shims separate for oil flow until pressurised, improving mid-speed control
  • Provide progressive damping: plush on small bumps, firm on large impacts
  • Available as coil springs, wave washers or o-rings to suit piston assemblies
  • Essential wear parts for every rebuild and for offroad, adventure or MX tuning

Recommended Pairings

Consider matching these with shock valving sets, Valving Shims and our Suspension Tools.
