The Ohlins HO149 STX 46 Supersport rear shock is a purpose-built replacement unit for the Honda CBR900RR. It is built around Ohlins race-derived damping architecture to improve rear-wheel control under braking, acceleration and cornering. This model uses a separated oil/gas design to help maintain consistent damping during demanding use.

Ohlins | Made to race, perfected to ride

The STX 46 Supersport range is designed for riders who want a more controlled, more tuneable rear end without compromising feel. HO149 focuses on predictable damping behaviour and clear feedback so chassis changes are easier to sense and evaluate.

Who this shock is for

Suited to riders using their CBR900RR for spirited road riding and track days who want more support and adjustability than a basic OEM-style shock. It is also a good fit when you need a serviceable performance shock that can be revalved and resprung to match your riding and tyres.

Shock design & features

This is a 46 mm piston STX (single-tube) shock with a hose-mounted remote reservoir, separating oil and gas for stable damping performance. The remote reservoir layout supports consistent behaviour when the shock is working hard and provides packaging flexibility on the bike.

Tuning controls

HO149 includes external rebound damping adjustment, compression damping adjustment and a length adjuster to help fine-tune chassis attitude. These controls allow you to balance grip, support and steering response to suit different tyres, surfaces and riding pace.

Before you install

• Confirm clearance and hose routing for the remote reservoir and ensure there is no contact through full suspension travel.
• Record your baseline settings before making changes so you can return to a known reference.
• Inspect linkage bearings and mounting hardware condition, as worn components can mask the benefits of a new shock.

Serviceability/lifecycle

As a fully rebuildable Ohlins unit, the HO149 can be serviced and tuned over its life with oil changes, seal replacement and internal damping updates as required. Regular servicing helps maintain damping consistency and protects internal components from wear.
