The Ohlins YA169 STX 46 Scooter Rear is a rear mono shock absorber developed for the Yamaha Exciter 155. Built around Ohlins’ proven damping architecture, it’s designed to deliver controlled chassis behaviour and consistent feel across varied road conditions. This unit uses a gas-pressurised, oil/gas separated design to help maintain stable damping during repeated impacts and heat build-up.
