The Ohlins YA151 STX 46 Adventure rear shock is a purpose-built replacement unit for the Yamaha TDM 850, aimed at improving control and consistency across mixed road and adventure-style use. Built around Ohlins’ STX architecture, it focuses on stable damping behaviour under changing loads and conditions. External adjusters allow you to fine-tune feel without dismantling the shock.

Ohlins | Made to race, perfected to ride

Developed with Ohlins’ motorsport-derived damping approach, this rear shock is designed to deliver predictable chassis behaviour and rider feedback. It suits riders who want a more controlled, tuneable setup than a typical standard shock.

Who this shock is for

  • Yamaha TDM 850 riders looking for more composure and consistency over varying surfaces
  • Touring and adventure-leaning use where load and road conditions can change ride to ride
  • Owners who want external damping and preload tuning to match tyres, pace, and payload

Shock design & features

This is an Ohlins STX 46 monotube rear shock with a separated oil and gas design for more consistent damping during sustained use. The body and valving are designed to support controlled damping response and stable operation as conditions change.

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Hydraulic spring preload adjustment for quick load compensation

Before you install

Confirm fitment for your exact Yamaha TDM 850 model and year, and check surrounding clearance and linkage/bush condition before installation. After fitting, set sag and then fine-tune compression and rebound to suit your tyres, typical load, and the roads/tracks you ride.

Serviceability/lifecycle

Ohlins shocks are designed to be serviceable, with internal components intended for inspection and maintenance over the product’s life. Regular servicing helps maintain damping consistency and reduces wear, particularly when used in wet, dusty, or heavily loaded conditions.
