The Ohlins YA139 STX 36 twin rear shock set is built for Yamaha XJR 1200 and XJR 1300 models that benefit from more controlled rear suspension behaviour. As a matched pair for twin-shock applications, it is designed to improve consistency, stability and feedback compared with ageing or tired original equipment. This unit uses a separated oil/gas layout to help maintain damping performance during extended riding.

Ohlins | Made to race, perfected to ride

Ohlins street shocks are developed with the same damping principles used across the brand’s competition products, then adapted for road use. The result is a rear suspension upgrade aimed at predictable control rather than harshness. For twin-shock motorcycles, the focus is on balance between left and right units and stable chassis attitude.

Who this shock is for

• Riders restoring or modernising the rear end of an XJR 1200 or XJR 1300 with a quality twin-shock package
• Owners who want clearer rear-tyre feel and better composure through corners and under braking
• Riders who value tunability to suit different road conditions and loads

Shock design & features

• STX 36 twin-shock architecture for rear fitment on twin-shock chassis
• Oil/gas separated design to support consistent damping behaviour as temperatures rise
• Matched pair supplied for balanced damping characteristics across both sides

Tuning controls

• Rebound damping adjustment to control return speed after bumps and weight transfer events
• Compression damping adjustment to manage support under load and road impacts
• Spring preload adjustment to set ride height and sag for rider, passenger and luggage use

Before you install

• Confirm fitment for Yamaha XJR 1200 / XJR 1300 and rear twin-shock mounting
• Set sag and preload first, then fine-tune compression and rebound based on ride feel and tyre behaviour
• Check clearance around guards, chain run and exhaust components after installation

Serviceability/lifecycle

Ohlins shocks are designed to be maintained. Periodic servicing helps keep damping performance consistent and extends component life, particularly on older motorcycles where road grime and heat cycles are common.
