The Ohlins TR623 STX 36 twin rear shock set is built for Triumph Street Cup and Street Twin riders who want a controlled, confidence-inspiring chassis feel on the road. This is a matched twin-shock solution designed to deliver consistent damping behaviour and clear feedback. It uses a gas-charged internal design to help maintain damping stability as conditions change.

Ohlins | Made to race, perfected to ride

Developed from Ohlins suspension know-how, the STX 36 Twin family focuses on ride quality, traction and predictable handling. The TR623 is intended as a direct-fit rear twin-shock upgrade for the listed Triumph models, with a balanced baseline aimed at real-world road riding.

Who this shock is for

  • Riders upgrading from basic twin shocks for better composure and tyre contact feel
  • Street riders who value stability through corners and under braking
  • Owners who want external adjustability to tailor the rear end to load and riding style

Shock design & features

This is a gas-charged emulsion-style rear shock design, intended to reduce damping fade and keep behaviour consistent during longer rides. As a twin-shock arrangement, it supports balanced rear suspension action and improved control compared with non-adjustable or lightly damped OE units.

Tuning controls

The TR623 provides external rebound damping adjustment, allowing you to fine-tune how quickly the rear returns after bumps and weight transfer. It also includes spring preload adjustment, so you can set ride height and support for rider weight and luggage.

Before you install

  • Confirm fitment for Triumph Street Cup and Street Twin before installation
  • Set sag and preload first, then refine rebound damping to suit your tyres and road conditions
  • Inspect linkage/bushings and mounting hardware condition during installation

Serviceability/lifecycle

Ohlins shocks are serviceable components designed to be maintained over their working life. Periodic servicing helps keep damping performance consistent and supports long-term reliability.
