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.

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.
