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.
