DescriptionThe whole story▼

Correct fork function is a safety-critical matter, and the K-Tech SBS-010 slider bush kit gives your Kawasaki ZX-6R, ZX-636 or ZX-RR the precision-engineered foundation it demands. Manufactured from hardened steel with a copper underlay and PTFE-coated contact surfaces, these replacement bushes restore factory-spec fork action while measurably reducing friction — keeping steering response accurate and predictable whether you are threading a chicane or braking hard into a hairpin.

Key Features

  • Hardened steel construction with copper layer for superior wear resistance and long service life
  • PTFE-coated sliding surfaces minimise friction for smoother, more consistent fork travel
  • Precision-dimensioned to OEM tolerances — inner diameter 39.70 mm, outer diameter 42.70 mm, height 20.00 mm, wall thickness 1.50 mm
  • Direct replacement for the factory bushes — no modifications required for a correct fit
  • Complete kit contains two bushes, covering both fork legs in a single purchase
  • Covers the full ZX-6R / ZX-636 / ZX-RR model range from 2005 through to 2026

Performance and Build Quality

Worn fork slider bushes are among the most common causes of vague steering feel and uneven fork damping. As the bushes deteriorate, side-play develops between the inner and outer fork tubes, introducing flex and inconsistency that no spring or damper adjustment can fully compensate for. The K-Tech SBS-010 kit addresses this at the root cause.

The hardened steel core provides the structural rigidity needed to maintain precise tube alignment under the lateral and axial loads experienced in hard braking and cornering. The copper interlayer acts as a sacrificial wear buffer, protecting both the bush and the fork tube from direct metal-to-metal contact. The PTFE surface treatment then reduces the coefficient of friction between the moving surfaces, allowing the fork to move freely and consistently throughout its stroke — a quality that is immediately perceptible in the rider's handling feedback.

Installation Note

These bushes are intended as a like-for-like replacement but installation requires fork disassembly and the use of specialist tools. K-Tech strongly recommends that fitting is carried out by an authorised K-Tech Service Centre to ensure correct seating, optimal performance and continued suspension safety.
