DescriptionThe whole story

If your ZX-10 R or ZX-10 RR front fork feels sticky, vague or simply worn through hard mileage, the K-Tech Slide Bushing Kit GBS-019 gives you a precise, long-lasting factory-fit replacement engineered for comfort and confidence across a full day's riding. Hardened steel construction with a copper coating and PTFE-treated contact faces eliminates the micro-friction that blunts fork response and fatigues your wrists over distance.

Key Features

  • Direct OEM replacement: machined to drop straight into the Kawasaki ZX-10 R and ZX-10 RR front fork without modification
  • Hardened steel shell with copper coating provides exceptional wear resistance and long service life under repeated hard braking and cornering loads
  • PTFE-coated contact surfaces dramatically reduce sliding friction, restoring crisp, linear fork action whether you are navigating commuter traffic or pushing through a track day
  • Complete kit contains two slide bushings — enough for a full front fork rebuild in one purchase
  • Covers the entire production run from 2011 through 2026, including both the ZX-10 R and the homologation ZX-10 RR variant

Why Fork Slide Bushings Matter for All-Day Riding

Worn slide bushings are one of the most overlooked causes of poor ride quality. As the original bushings degrade, lateral play builds up in the fork legs, creating a subtle but persistent vagueness in the front end. On long rides this transmits directly to your hands and shoulders, adding fatigue that compounds over kilometres. Fresh K-Tech GBS-019 bushings restore the tight, low-friction interface the Kawasaki engineers specified, so the fork tracks cleanly through road imperfections without the steering chatter that worn items produce. The PTFE surface also means the fork stiction that makes the front feel wooden over slow bumps is effectively eliminated — the fork begins moving exactly when the road asks it to, not a moment later.

Build Quality

K-Tech has produced suspension components for World Superbike and BSB-level teams for decades, and the same material disciplines carry through to their replacement bushing kits. Each bushing in the GBS-019 set is manufactured from hardened steel and then copper-coated to prevent galling between metal surfaces during installation and in service. The PTFE layer is applied to the sliding contact face to keep kinetic friction minimal throughout the bushing's working life. With an inner diameter of 43.00 mm, outer diameter of 47.00 mm, a height of 15.00 mm and a wall thickness of 2.00 mm, the dimensions are held to tolerances that ensure a secure, rattle-free fit inside the fork leg.

Fitment & Compatibility

The K-Tech GBS-019 slide bushing kit is designed specifically for the following models:

  • Kawasaki ZX-10 R — 2011 to 2026
  • Kawasaki ZX-10 RR — 2011 to 2026

Always verify the front fork inner tube diameter of 43 mm before fitting. Installation requires specialist fork tools and knowledge; K-Tech recommends fitting be carried out by an authorised K-Tech Service Centre to ensure maximum performance and safety.
