The Ohlins YA420 STX 46 Supersport rear shock is built for riders who want controlled, predictable damping from a purpose-designed mono shock. Developed from Ohlins racing experience, it focuses on improving chassis stability and rear tyre contact under real-world sport riding and track conditions. This unit uses a gas-pressurised, oil/gas separated design to maintain damping consistency during hard use.

Ohlins | Made to race, perfected to ride

Part of the STX 46 Supersport family, this rear shock is engineered around a modern piston-and-shim damping architecture intended to deliver clear feedback and stable support. The design targets improved traction and control without compromising ride composure.

  • Track day and fast road riders looking for consistent damping and better drive out of corners
  • Owners who want external adjustability for tailoring feel to tyres, pace and surfaces
