The Ohlins HD791 STX 36 Blackline shock pair is a rear twin-shock upgrade for Harley-Davidson Street 500 and Street 750 models. Built around Ohlins STX damping architecture, it’s designed to deliver controlled, consistent suspension behaviour for everyday road use. The Blackline finish suits custom and classic styling while keeping the focus on functional performance.

Ohlins | Made to race, perfected to ride

Ohlins suspension is developed with a strong engineering focus on damping control and ride consistency. This STX 36 Blackline pair brings that approach to Harley-Davidson twin-shock applications where stability and comfort both matter. It’s aimed at riders who want a more settled rear end without changing the character of the bike.

Who this shock is for

Suited to Street 500 and Street 750 riders looking for a premium rear suspension solution for commuting, weekend rides, or a tasteful custom build. It’s also a good match for those who want more adjustability than typical cruiser shocks, with the ability to tailor feel to load and road conditions.

Shock design & features

This is an emulsion-style monotube shock design, using a single internal volume for oil and gas. The STX 36 Blackline platform is built for consistent damping response and durability in a compact twin-shock format, with a finish intended to complement darker or understated builds.

Tuning controls

Adjustability includes compression damping, rebound damping, and spring preload. These controls let you refine chassis support, comfort over bumps, and how quickly the rear settles after impacts or during corner exits, while also allowing you to compensate for passenger or luggage load.

Before you install

Confirm fitment for Harley-Davidson Street 500 and Street 750 and note that this listing is for a rear shock pair. After installation, set preload and damping to suit your usual riding load and tyre choice, then fine-tune in small steps to balance comfort and control.

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.
