The Ohlins HM250 STX 46 Supersport rear shock is a track-focused replacement unit built to deliver controlled damping and clear tyre feedback on the Harris Magnum 4. It uses a gas-pressurised damping system to help maintain consistency as temperatures and loads change. Independent damping circuits allow you to tune the bike to suit surface grip and riding style.

Ohlins | Made to race, perfected to ride

Developed from Ohlins road racing experience, the STX 46 Supersport platform is aimed at riders who want predictable chassis behaviour and repeatable setup changes. It is intended for rear mono-shock applications where stability and traction are priorities.

Who this shock is for

Suited to riders using the Harris Magnum 4 in spirited road riding, track days, or competition where consistent feel and tunability matter. It is most relevant if you are chasing improved control during braking, corner entry, and drive off the turn compared with a basic rear shock.

Shock design & features

This is a gas-pressurised rear shock from the Ohlins STX 46 Supersport family. The pressurised design is used to support stable damping performance and resist fade during repeated hard use.

Tuning controls

The shock provides independent damping adjustment for compression and rebound, allowing you to balance support, grip, and stability. This makes it easier to separate changes needed for bump compliance from those needed for chassis control.

Before you install

Confirm fitment for your Harris Magnum 4 and inspect linkage and bearings so the shock can move freely through its stroke. Once installed, set sag and confirm adjusters are operating through their full range before fine-tuning on track or road.

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.
