The Ohlins YA555 STX 36 Twin shock is a rear suspension upgrade developed for the Yamaha XJR 1300. Built around Ohlins monotube damping architecture, it’s designed to deliver controlled chassis movement and consistent damping feel across changing road conditions. Adjustment features allow you to tune the shock’s response to suit your load, tyres and preferred pace.

Ohlins | Made to race, perfected to ride

Ohlins street shocks draw on racing development, with a focus on predictable damping behaviour and clear feedback. The aim is stable handling and traction you can trust, rather than a harsh ride. This unit is supplied as a twin rear shock set-up for the XJR 1300 platform.

Who this shock is for

Suited to riders who want more control and support from the rear of the bike, whether commuting, weekend road riding, or carrying a passenger and luggage. It’s also appropriate if you’re chasing more consistent feel during repeated hard acceleration and braking. If your current suspension feels vague, underdamped, or inconsistent over longer rides, this type of upgrade is typically where you notice the difference first.

Shock design & features

This STX 36 Twin design uses a gas-pressurised monotube layout with the oil and gas separated. That separation helps maintain damping consistency as the shock works through repeated strokes. As a twin shock arrangement, it supports the rear of the motorcycle in a balanced way while maintaining good feedback through the chassis.

Tuning controls

The YA555 provides external adjustments for rebound damping, compression damping, and spring preload. Rebound adjustment lets you control how quickly the rear recovers after a bump or under load transfer. Compression adjustment influences support under acceleration, braking, and sharper impacts, while preload is used to set ride height and sag for your weight and typical riding load.

Before you install

  • Confirm the bike model and year compatibility for your Yamaha XJR 1300 application.
  • Set sag and preload for your normal riding load before fine-tuning damping.
  • After installation, re-check fasteners and clearances, and make one adjustment at a time when tuning.
