The Ohlins KA446 STX 36 twin shock is a rear suspension unit developed for the Kawasaki Zephyr 1100. Built around Ohlins’ established damping architecture, it’s aimed at improving stability, traction and chassis feedback for road riding. The design uses a gas-pressurised, oil/gas separated layout to help maintain consistent damping as conditions change.

Ohlins | Made to race, perfected to ride

STX 36 twin shocks carry Ohlins race-derived damping know-how into a street-focused package. The goal is predictable support through corners and under braking, with a controlled ride that stays composed over changing surfaces.
