The Ohlins STX 36 Supersport rear shock for the Kawasaki Ninja 250(R) and Ninja 300 (EX300) is built to deliver stable, predictable damping and clear chassis feedback. It uses a pressurised gas/oil-separated damping layout to help maintain consistent control as conditions change. With external adjustments, it supports proper setup for spirited road riding and track-focused use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins’ racing suspension background, the STX 36 Supersport platform focuses on controlled damping behaviour and usable tuning range. The aim is improved rear-wheel contact and stability through corners and under braking, without making setup overly complicated.

Who this shock is for

Suited to riders who want more support, feel and consistency than a standard rear shock typically provides. It’s a practical choice for riders doing track days, commuting with a performance focus, or anyone wanting a more planted rear end with the ability to tune the bike to tyres, pace and road surface.

Shock design & features

This is an STX 36 Supersport rear mono shock with a gas-pressurised, oil/gas separated damping system. The architecture is designed to reduce damping fade and maintain repeatable performance across longer, harder sessions. The overall design prioritises stable damping control and traction-focused behaviour.

Tuning controls

• Rebound damping adjustment to control how quickly the shock extends after compression.
• Compression damping adjustment to manage support and control when the shock is being compressed by bumps, braking load transfer, and cornering forces.
• Length/ride-height adjustment to fine-tune rear ride height and chassis attitude.

Before you install

Confirm correct fitment for your exact model and year, then set sag and verify spring preload for your riding weight and typical load. After installation, check clearances through full suspension travel and ensure the adjusters are accessible for tuning.

Serviceability/lifecycle

Like all performance shocks, the best results come from routine servicing to keep oil condition, seals and gas pressure in spec. Regular maintenance helps preserve consistent damping feel and ensures your adjustments remain effective over time.
