The Ohlins YA156 is an STX 36 twin rear shock set-up designed for Yamaha XJR 1200 and XJR 1300 applications. It’s built around stable, controlled damping to improve chassis composure and tyre contact across real-world road conditions. As a twin-shock rear arrangement, it suits riders chasing more consistent feel and better control from the standard suspension.

Ohlins | Made to race, perfected to ride

Ohlins street shocks apply proven damping architecture and build quality to deliver predictable responses at the rear tyre. The focus is on maintaining support without harshness, so the bike remains settled through braking, turn-in and acceleration. This unit is intended to integrate cleanly with the XJR’s twin-shock chassis layout.

Shock design & features

This is a gas-pressurised rear shock design to help reduce cavitation and keep damping behaviour consistent as temperatures rise. The STX 36 twin configuration is aimed at delivering controlled motion and improved stability under load changes. The core intent is repeatable damping and clear feedback rather than overly soft or overly firm behaviour.

Tuning controls

The YA156 provides external adjustability for rebound and compression damping, allowing you to balance comfort, grip and chassis support to suit your tyres, roads and riding style. Spring preload adjustment lets you set sag correctly for rider weight and intended use. These controls are designed for practical tuning without needing internal modifications.

Before you install

• Confirm the bike model and year match your Yamaha XJR 1200 / XJR 1300 fitment requirements.
• Set rider sag via preload before evaluating damping changes.
• Make adjustments one at a time and road test to understand the effect on support and compliance.
• Inspect linkage, mounts and bushes during installation to ensure the shocks can work as intended.

Serviceability/lifecycle

Like all performance dampers, regular servicing helps maintain oil condition, seal integrity and consistent damping response over time. If ride quality changes, adjusters lose effectiveness, or you see any signs of leakage, it’s a good indicator the shocks are due for inspection and service.
