The Ohlins YA501 STX 46 Street rear shock is a street-focused replacement unit for the Yamaha MT-01, built around Ohlins race-derived damping know-how. It’s designed to improve chassis control and tyre contact for more consistent feel through braking, turn-in and drive. This is an oil/gas separated monotube shock rather than an emulsion design.

Ohlins | Made to race, perfected to ride

STX 46 Street units are engineered for real-world road use, targeting stability and predictable grip across mixed surfaces and pace changes. The YA501 is intended to deliver controlled damping response without sacrificing ride quality on the street.

Shock design & features

  • STX monotube architecture with oil and pressurised gas separated to help maintain damping consistency.
  • Rear mono-shock fitment for the Yamaha MT-01 application.
  • Race-developed internal valving approach aimed at improving traction and chassis stability under load changes.

Tuning controls

  • Rebound damping adjustment for fine control of how quickly the shock extends after bumps and acceleration loads.
  • Compression damping adjustment to tailor support under braking and during cornering loads.
  • Hydraulic spring preload adjustment to set sag and ride height balance more conveniently.

Base setup (factory preset)

Each unit is supplied with an Ohlins baseline setting intended as a safe starting point for road riding. Set preload to achieve correct sag first, then adjust rebound and compression in small steps to match your tyres, load and preferred response.

Before you install

  • Confirm clearances around the reservoir/hydraulic preload components during full suspension travel.
  • Inspect linkage and mounting hardware condition; worn bearings can mask the benefit of a quality shock.
  • After installation, re-check fastener torque and verify free movement through the stroke.

Serviceability/lifecycle

As a rebuildable Ohlins unit, the YA501 can be serviced to maintain performance over time. Regular oil and seal service helps keep damping consistent, especially if the bike sees frequent spirited road use.
