The Ohlins KA128 is a rear TTX RT shock absorber developed for the Kawasaki ZZ-R 1400 (Ninja ZX-14R). It uses a gas-pressurised damping system to maintain consistent control as conditions and temperatures change. Built around independent damping circuits, it is intended for riders who want clear feedback and tunability without compromising stability.

Ohlins | Made to race, perfected to ride

Ohlins TTX RT units bring race-derived damping architecture to street and supersport applications. The focus is predictable behaviour through the stroke, with damping control that remains consistent when pushed harder.

Who this shock is for

Suited to ZZ-R 1400 (Ninja ZX-14R) riders chasing improved chassis control for fast road riding or track use. It’s a fit for those who value traction and stability under heavy braking and on corner exit, and who plan to tune settings to suit tyres, load and riding style.

Shock design & features

This is a gas-pressurised, oil/gas separated design from the Ohlins TTX RT family. The layout is built around independent compression and rebound circuits to help maintain damping accuracy and reduce sensitivity to heat during extended riding.

Tuning controls

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

Before you install

  • Confirm fitment for your exact Kawasaki ZZ-R 1400 (Ninja ZX-14R) model and year.
  • Set sag and preload first, then fine-tune rebound and compression to match your tyres and typical load.
  • Inspect linkage bearings and mounting hardware condition during installation.

Serviceability/lifecycle

Ohlins shocks are designed to be serviced and re-valved as required. Periodic servicing helps keep damping performance consistent and is recommended when usage is demanding or conditions are harsh.

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.
