The Ohlins HO890 TTX RT rear shock is built for riders chasing predictable grip and clear feedback on the Honda NSR Mini. Based on Ohlins race-developed damping concepts, it is designed to keep the chassis settled under braking, through the apex and on corner exit. Its gas-pressurised layout helps maintain consistent damping when the pace lifts.
