The Ohlins YA203 STX 46 Street rear shock is built to improve chassis control and stability for the Yamaha BT 1100 Bulldog in road use. Developed from Ohlins race technology, it delivers consistent damping behaviour and clearer feedback through the rear tyre. This unit uses a gas-pressurised design to help maintain damping consistency as conditions change.

Ohlins | Made to race, perfected to ride

Ohlins STX 46 Street shocks are engineered for controlled damping response and predictable handling on the road. The YA203 is a direct-fit rear mono shock solution intended to sharpen feel without compromising day-to-day ride quality.

Shock design & features

  • Gas-pressurised monotube architecture for stable damping performance
  • Ohlins STX 46 Street product family design
  • Rear mono shock application for Yamaha BT 1100 Bulldog

Tuning controls

This shock provides rebound damping adjustment to tailor the bike’s response over bumps and during cornering transitions. It also includes a remote hydraulic spring preload adjuster to quickly set sag for load changes such as luggage or a passenger.

Before you install

  • Confirm the correct fitment for your exact Yamaha BT 1100 Bulldog model and year
  • Set spring preload and rebound to a sensible baseline before road testing
  • Re-check fastener torque and sag after the first rides

Serviceability/lifecycle

Like other Ohlins road shocks, the YA203 is designed to be maintained over its service life. Periodic oil and wear-part servicing helps keep damping consistent and protects internal components.
