The Ohlins HO645 rear shock is built for the Honda XRV 750 Africa Twin and is intended to improve control and comfort across mixed-surface adventure riding. It is designed to maintain composure over rough tracks while supporting stable handling when the bike is loaded. As part of the STX 46 Adventure family, it focuses on consistent damping in demanding conditions.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong focus on damping control and repeatable feel. This unit is engineered as a direct-fit rear mono shock solution for the Africa Twin, aimed at riders who want a more controlled and confidence-inspiring chassis response.

Shock design & features

This is a monotube shock with a separate gas and oil arrangement to help maintain damping consistency under sustained use. The STX 46 Adventure architecture is designed for durability and stable operation across long days on variable terrain.

Tuning controls

The HO645 provides external adjustment for rebound damping and compression damping, allowing you to tailor response for terrain, tyres, and riding style. It also includes spring preload adjustment to help set ride height and balance for rider weight and luggage.

Base setup (factory preset)

The shock is supplied with an Ohlins spring fitted from the factory. A baseline setup is established by Ohlins to suit the intended application, giving you a solid starting point before fine-tuning preload, rebound, and compression to preference.

Before you install

  • Confirm fitment for Honda XRV 750 Africa Twin and rear mono mounting position before installation.
  • Set rider sag via spring preload first, then fine-tune rebound and compression damping.
  • After installation, re-check fasteners and clearance through suspension travel.

Serviceability/lifecycle

Like all performance shocks, routine servicing helps maintain damping performance over time. Regular inspection and periodic rebuilds are recommended, particularly if the bike is used frequently in dusty, wet, 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.
