The Ohlins TR628 STX 36 Twin shock set is a rear twin-shock replacement for Triumph Bonneville, Scrambler 900 and Thruxton 900 models. Built around Ohlins STX architecture, it is designed to deliver controlled, consistent damping and clear feedback at the rear wheel. This unit uses a gas-pressurised design to help maintain damping performance during sustained riding.

Ohlins | Made to race, perfected to ride

Before you install
