The Ohlins STX 46 MX rear shock for KTM 85 SX is built around a pressurised, separated oil and gas design to help maintain damping consistency in demanding off-road conditions. It’s intended for riders who want clear feedback and controlled chassis movement across braking bumps, ruts and jump landings. Supplied without a spring, it’s designed to be matched with an appropriate rate during setup.
