The Ohlins YA427 STX 36 twin rear shocks are a matched pair designed to improve rear-end control and consistency on the Yamaha V-Max. Built around Ohlins’ STX architecture, they focus on stable damping behaviour across real-world road conditions. These units are intended for riders who want a more controlled chassis feel and clear feedback without making the bike harsh.

Ohlins | Made to race, perfected to ride

Ohlins twin-shock systems are developed to deliver predictable damping, reliable heat management and repeatable tuning. The YA427 kit applies that approach to the V-Max rear end, aiming for better composure under acceleration and through corners.

Shock design & features

  • STX 36 twin-shock design for the V-Max rear suspension layout
  • Oil and gas are separated for more consistent damping during sustained use
  • Matched left/right units suited to twin rear mounting

Tuning controls

  • Spring preload adjustment to suit load, sag and ride height targets
  • Rebound damping adjustment to control extension speed and grip feel
  • Compression damping adjustment to manage support under bumps and load transfer

Before you install

  • Confirm clearance and hardware condition at the upper and lower mounts before fitting
  • Set sag and preload first, then fine-tune rebound and compression one change at a time
  • If you ride with a passenger or luggage, plan on revisiting preload and damping settings

Serviceability / lifecycle

These shocks are fully serviceable and are designed to be maintained with periodic oil and seal replacement. Regular servicing helps preserve damping consistency and keeps adjusters working smoothly 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.
