The Ohlins TR851 is a rear STX 46 shock absorber developed for the Triumph Sprint ST, aimed at improving control and consistency over a wide range of road conditions. It uses a monotube layout with a separated gas chamber to keep damping stable as temperatures and loads change. Adjustment is provided for rebound damping and compression damping, with hydraulic spring preload to suit varying rider, luggage and pillion loads.

Ohlins | Made to race, perfected to ride

Ohlins suspension is designed around predictable damping behaviour, with a focus on control, feel and serviceability. The STX platform is intended for real-world riding where surface quality and load can vary ride to ride.

Who this shock is for

Riders using the Sprint ST for sport-touring and longer days who want a more controlled rear end through changing surfaces and conditions. It also suits those who regularly change load (solo to luggage and/or pillion) and want an easier way to reset balance without compromising damping quality.

Shock design & features

  • Monotube STX architecture with oil/gas separation for consistent damping.
  • External reservoir design to support stable performance in demanding use.
  • Built as a serviceable unit, intended to be maintained rather than treated as disposable.

Tuning controls

  • Rebound damping adjustment for rear wheel control after bumps and during weight transfer.
  • Compression damping adjustment to manage support and impact absorption.
  • Hydraulic spring preload adjustment to set ride height and balance for different loads.

Before you install

  • Confirm the shock is matched to your exact Triumph Sprint ST model and year before fitting.
  • Set sag and preload first, then fine-tune rebound and compression to suit your tyres, load and typical roads.
  • After installation, re-check fastener torque and clearances through full suspension travel.

Serviceability/lifecycle

This Ohlins unit is designed to be serviced with periodic oil and seal replacement to keep damping consistent over time. Regular maintenance intervals depend on use conditions, especially if the bike sees frequent rough-road touring.

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.
