The Ohlins HD764 STX 36 Blackline rear shock pair is built for Harley-Davidson Dyna models needing more controlled damping without losing the classic look. This twin-shock setup suits everyday road use and spirited riding where stability and comfort matter. The Blackline finish is designed to complement traditional and custom builds.

Ohlins | Made to race, perfected to ride

STX is Ohlins’ monotube architecture with a separated gas and oil design to maintain damping consistency. This model is supplied as a matched rear pair for twin-shock fitment.

Who this shock is for

  • Harley-Davidson Dyna FXD riders wanting improved control and compliance over varied road surfaces
  • Owners building a classic or custom look who still want modern damping behaviour
  • Riders who want external adjusters rather than a fixed, non-serviceable shock

Shock design & features

  • STX monotube construction with separated gas and oil (not emulsion)
  • Rear twin-shock configuration supplied as a pair
  • Blackline styling to suit cruiser and custom applications

Tuning controls

  • Spring preload adjustment
  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm fitment for your Harley-Davidson Dyna FXD application before installation
  • Set sag and preload first, then fine-tune rebound and compression to suit load and road conditions
  • Check clearances and hardware condition when fitting twin rear shocks

Serviceability/lifecycle

Ohlins shocks are designed to be maintained and reconditioned over their service life. Regular servicing helps keep damping performance consistent and extends component longevity.

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.
