The Ohlins TR613 rear twin shock set is built for riders who want controlled damping and consistent feel from a quality road-focused suspension upgrade. As part of the STX 36 twin shock family, it’s designed to improve stability and feedback without compromising everyday rideability. This unit uses a separated oil/gas damping layout to help maintain damping control through varied conditions.

Ohlins | Made to race, perfected to ride

Ohlins twin shock units combine proven damping design with practical adjustability for real-world road use. The focus is predictable chassis behaviour, improved tyre contact, and clear feedback you can trust when pace or surfaces change.

Who this shock is for

Suited to Triumph Street Cup and Street Twin owners running twin rear shocks who want more control than standard suspension can provide. A good fit for riders who value stability under braking and better composure through corners, whether riding briskly on the road or doing occasional track work.

Shock design & features

This is an Ohlins STX 36 twin shock design with separated oil/gas damping. The layout is intended to support consistent damping performance and better heat management than simpler designs. Supplied with black springs as fitted by Ohlins for this application.

Tuning controls

Adjustability includes rebound damping and compression damping, allowing you to tune the bike’s response for comfort, grip, and stability. Spring preload adjustment is also provided to set ride height and balance for rider load and intended use.

Before you install

• Confirm the model fitment for your Triumph Street Cup or Street Twin and ensure your bike retains the twin-shock rear configuration.
• Set sag and spring preload first, then fine-tune rebound and compression to suit your roads and riding style.
• After installation, re-check fasteners and clearance through the suspension travel.

Serviceability / lifecycle

Ohlins shocks are designed to be serviced to keep damping performance consistent over time. Routine servicing helps maintain oil condition and internal wear parts, especially if the bike sees frequent hard use.
