The Ohlins YA420 STX 46 Supersport rear shock is built for riders who want controlled, predictable damping from a purpose-designed mono shock. Developed from Ohlins racing experience, it focuses on improving chassis stability and rear tyre contact under real-world sport riding and track conditions. This unit uses a gas-pressurised, oil/gas separated design to maintain damping consistency during hard use.

Ohlins | Made to race, perfected to ride

Part of the STX 46 Supersport family, this rear shock is engineered around a modern piston-and-shim damping architecture intended to deliver clear feedback and stable support. The design targets improved traction and control without compromising ride composure.

Who this shock is for

  • Riders refreshing worn suspension on a Yamaha YZF 750 R and wanting a more controlled rear end
  • Track day and fast road riders looking for consistent damping and better drive out of corners
  • Owners who want external adjustability for tailoring feel to tyres, pace and surfaces

Shock design & features

  • STX 46 Supersport monotube-style rear shock construction
  • Gas-pressurised, oil/gas separated layout for consistent damping performance
  • Developed with Ohlins race-derived valving approach for stability and tyre contact

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm fitment for your exact Yamaha YZF 750 R model and year prior to installation
  • Set sag and verify spring suitability for rider weight and use
  • After installation, re-check fasteners and alignment after an initial ride session

Serviceability/lifecycle

This Ohlins shock is designed to be serviced and re-valved as required. Periodic oil and seal maintenance helps preserve damping control and extends component life, especially if the bike sees regular hard road use or track 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.
