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.
