The Ohlins YA243 STX 46 Supersport rear shock is designed to give the Yamaha YZF 750 SP a controlled, predictable rear end under hard use. Built around Ohlins race-derived damping architecture, it focuses on consistent behaviour through braking, turn-in and corner exit. It is a dedicated rear mono shock unit intended for riders who want tunability and clear feedback from the chassis.

Ohlins | Made to race, perfected to ride

STX 46 Supersport units are engineered for track-focused handling while remaining suitable for performance road riding. The damping system is designed to maintain stability and traction when loads change quickly, helping the bike stay composed as conditions and pace vary.

Shock design & features

This is an oil/gas separated shock design to support consistent damping during repeated high-load cycles. The STX architecture separates functions within the damper to deliver a more controlled response through the stroke and improve feel at the tyre contact patch.

Tuning controls

The YA243 provides external rebound damping adjustment and external compression damping adjustment to fine-tune balance and grip. It also includes length adjustment to help set ride height and chassis attitude without relying solely on spring preload changes.

Before you install

  • Confirm clearance and hose/reservoir routing (where applicable) and ensure the adjusters remain accessible once fitted.
  • Set sag and baseline damping after installation, then change one parameter at a time during testing.
  • Use the recommended Ohlins oil for servicing to maintain intended damping performance.

Serviceability/lifecycle

This Ohlins unit is fully serviceable and intended to be maintained as a performance component. Regular inspection and periodic servicing help keep damping consistent and protect internal wear surfaces over the long term.

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.
