The Ohlins YA343 STX 46 Supersport rear shock is built for riders chasing consistent chassis control and clear feedback from the rear tyre. Developed from Ohlins race-derived architecture, it is designed to maintain predictable damping behaviour through repeated hard use. This unit suits the Yamaha YZF R1 platform with a focus on precise tuning rather than one-size-fits-all feel.

Ohlins | Made to race, perfected to ride

STX 46 Supersport shocks are engineered around a modern monotube design aimed at delivering stable damping response and strong feel at lean. The YA343 is intended for riders who want a purposeful suspension package for track-focused riding and controlled road use.

Who this shock is for

  • Track day riders wanting stronger rear support and clearer grip feedback
  • Riders who regularly adjust setup for different tyres or conditions
  • Owners seeking a dedicated Ohlins rear mono shock solution for the YZF R1

Shock design & features

This is a rear mono shock using Ohlins STX 46 Supersport architecture with oil and gas separated for more consistent damping behaviour during demanding sessions. It is designed to provide stable support under braking and predictable traction as load transfers through the rear end.

Tuning controls

The YA343 provides external adjustment for rebound damping and compression damping, along with a length adjustment to help fine-tune chassis attitude. These controls allow the shock to be matched to rider preference, tyre choice, and track conditions without internal modification.

Before you install

  • Confirm correct fitment for your Yamaha YZF R1 and check clearance through full suspension travel.
  • Set sag and baseline adjustments before fine-tuning damping.
  • Inspect linkages and bearings for wear so the shock can work as intended.

Serviceability/lifecycle

Like all performance suspension, this Ohlins unit is designed to be serviced and re-oiled as part of normal ownership. Periodic servicing helps preserve damping consistency and keeps adjustment changes meaningful over time.

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.
