The Ohlins STX 46 Street rear shock is designed to replace the standard rear unit on the Kawasaki Ninja 650 (EX650) and Z 650, with a focus on controlled damping and consistent feel. It uses a gas-pressurised design to help maintain damping stability as conditions change. Built around Ohlins road and race development, it aims to improve rear-wheel contact and chassis composure without compromising everyday rideability.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing know-how and adapted for real-world road use, the STX 46 Street platform is intended to deliver predictable response and clear feedback. It’s a direct-fit style upgrade that targets control and confidence rather than comfort-only changes.

Shock design & features

This is a gas-pressurised rear mono shock with separated oil and gas to support consistent damping behaviour. The internal layout is intended to reduce fade and maintain stable response during repeated high-load events such as spirited road riding.

Tuning controls

The shock provides rebound damping adjustment and compression damping adjustment, allowing you to tune support and grip to suit tyres, load, and riding style. These adjusters are intended to help balance chassis attitude under braking, turn-in, and acceleration.

Who this shock is for

Suited to riders who want more control and clearer rear-end feedback than a typical OEM shock, particularly when pace increases or the bike is ridden harder on variable surfaces. It’s also relevant if you regularly ride with luggage or a passenger and want greater tuning range.

Before you install

Confirm the correct application for your exact model and year, then check clearances and mounting condition during installation. After fitment, set sag correctly and make small, methodical changes to rebound and compression so you can feel what each adjustment is doing.
