The Ohlins YA639 TTX RT rear shock is built for the Yamaha YZF R6, with a focus on control, feel and repeatable damping behaviour. Its twin-tube TTX layout is designed to keep damping forces consistent as conditions change. This unit is oil and gas separated to help maintain stable performance during sustained hard use.

Ohlins | Made to race, perfected to ride

Developed from Ohlins racing suspension architecture, the TTX RT platform targets traction and chassis stability when you are pushing the pace. It is intended for riders who want clearer feedback and a wider, more usable tuning range from the rear of the bike.

Shock design & features

  • Twin-tube TTX construction for controlled, consistent damping behaviour
  • Oil/gas separated design to support stability during long, demanding sessions
  • Rear mono shock configuration for the Yamaha YZF R6 application

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment
  • Hydraulic spring preload adjustment

Base setup (factory preset)

This shock is supplied with an Ohlins baseline setting intended as a safe starting point. From there, use the adjusters to balance grip, support and recovery speed to suit your tyres, riding style and track surface.

Before you install

  • Confirm the shock suits your Yamaha YZF R6 model and year before fitting
  • Set sag and preload first, then fine-tune compression and rebound
  • If your riding weight or use-case differs from standard, consider checking spring suitability before setup work

Serviceability/lifecycle

As a rebuildable Ohlins unit, routine servicing helps keep damping consistency and adjustment range where it should be. Service intervals depend on use intensity and environmental 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.
