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.

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.
