The Ohlins YA438 STX 46 Street is a rear shock absorber built to improve control and feedback on the Yamaha RD 500 LC in real-world road use. Developed from Ohlins race-derived damping know-how, it focuses on consistent response and predictable chassis behaviour. The design uses a gas-charged, oil/gas separated layout to help maintain damping stability during sustained riding.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are engineered to deliver repeatable damping performance with clear rider feel. The YA438 is part of the STX 46 Street family, aimed at riders who want a more controlled rear end without turning the bike into a track-only setup.

Shock design & features

  • STX 46 Street architecture tuned for road riding consistency and feedback
  • Gas-charged, oil/gas separated damping system to support stable performance as conditions change
  • Rear mono-shock fitment for the Yamaha RD 500 LC application

Tuning controls

  • Rebound damping adjustment to refine rear-wheel control and recovery
  • Compression damping adjustment to tailor support under load and chassis attitude
  • Hydraulic spring preload adjustment for practical ride-height and balance changes without removing the shock

Base setup (factory preset)

This shock is supplied with an Ohlins baseline setting intended to suit the standard fitment and typical road use. From there, adjustments let you fine-tune for rider weight, tyres, and how you want the bike to behave through bumps, braking and corner exits.

Before you install

  • Confirm all mounting hardware and clearances suit your RD 500 LC configuration
  • Check linkage/bush condition and service as needed before fitting a new shock
  • Set sag and then tune damping incrementally to suit your riding conditions

Serviceability/lifecycle

Like other Ohlins units, the YA438 is designed to be maintained with periodic servicing to keep damping performance consistent over time. Regular inspection and scheduled oil/seal service will help preserve ride quality and control.
