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.

Öhlins Motorcycle Suspension Warranty

New Öhlins motorcycle shock absorbers, front forks and cartridge kits supplied by Teknik Motorsport are covered by the applicable Öhlins manufacturer’s warranty against defects in materials and workmanship.

Teknik Motorsport is an authorised Öhlins Service Centre and administers warranty claims in accordance with the Öhlins warranty conditions. The service intervals below form part of the maintenance requirements for Öhlins products supplied and supported by Teknik Motorsport.

This warranty is in addition to the consumer guarantees that apply under the Australian Consumer Law.

  • Registered motorcycles — non-competition road use Five years, subject to correct application, installation, setup and servicing every: 20,000 km or two years, whichever occurs first.
  • Registered motorcycles — adventure and light off-road use Five years, subject to correct application, spring rate, setup and servicing every: 10,000 km or annually, whichever occurs first.
  • Unregistered or competition motorcycles Two years for eligible Öhlins MX and Enduro products, subject to inspection every ten hours and servicing every: 30 operating hours or annually, whichever occurs first.

Compliance with the applicable service interval is a condition of the Öhlins manufacturer’s warranty. Evidence of servicing may be required when a warranty claim is assessed.

A seal leak, loss of damping performance or internal wear arising after the prescribed service interval has been exceeded will be treated as a service or maintenance issue rather than a manufacturing defect.

Warranty repairs

Öhlins suspension products are designed to be serviced and repaired. Where a warranty claim is approved, the normal remedy is repair of the customer’s original suspension unit using genuine Öhlins replacement parts.

Replacement of a complete shock absorber, fork or cartridge kit is not automatic and would normally occur only where the product has suffered a manufacturing failure that cannot reasonably be repaired. This is at Ohlins discretion. 

Öhlins spare parts and service kits

Öhlins spare parts, seals, bushes, service kits, springs, fluids and individual components are covered only against defects present when supplied.

No fixed age-based warranty applies to wear items, service parts or consumable components. Wear, deterioration, contamination, incorrect installation and damage caused by another component are not manufacturing defects.

Öhlins gives the customer a meaningful five-year warranty on products (Units), provided the suspension is maintained as suspension should be maintained. Teknik supports that warranty locally, can inspect the product properly, and can repair it with genuine parts rather than discarding it.
