The Ohlins HO890 TTX RT rear shock is built for riders chasing predictable grip and clear feedback on the Honda NSR Mini. Based on Ohlins race-developed damping concepts, it is designed to keep the chassis settled under braking, through the apex and on corner exit. Its gas-pressurised layout helps maintain consistent damping when the pace lifts.

Ohlins | Made to race, perfected to ride

Developed from Ohlins competition experience, the TTX RT platform focuses on stability, traction and repeatable feel. The HO890 is a direct-fit rear mono shock application for the NSR Mini.

Who this shock is for

  • Riders using an NSR Mini for track work who want more control and consistency from the rear end
  • Owners looking to improve drive grip on corner exit and stability through braking zones
  • Those who value precise damping response and clear chassis feedback

Shock design & features

  • TTX RT rear shock design with a gas-pressurised damper to help reduce fade
  • Race-proven valving aimed at improving traction and stability
  • High-speed damping response for sharper chassis control

Tuning controls

  • Rebound damping adjustment
  • Compression damping adjustment

Before you install

  • Confirm linkage, bearings and mounting hardware are in good condition before fitting
  • Set sag and balance front-to-rear after installation to get the most from the damping adjusters
  • If you are changing tyre type or pace significantly, consider a tailored setup to suit your use

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.
