K-Tech Fork Slide Bush Kit Honda CBR 1000 RR-R / SP SC82 (2020-2026) GBS-019

Designed exclusively for the Honda CBR 1000 RR-R and SP SC82 from 2020 to 2026, the K-Tech GBS-019 slide bush kit restores the front fork to factory-fresh precision while upgrading the materials beyond original specification. Whether you spend long days on track or demand consistent chassis feedback on every ride, these bushes deliver the smooth, friction-free stroke that keeps your suspension working exactly as intended.

Key Features

• Hardened steel construction with copper coating resists wear and corrosion far beyond the service life of standard OEM bushes.
• PTFE-coated contact surfaces reduce sliding friction to a minimum, giving the fork a supple, responsive action from the first millimetre of travel.
• Precise dimensional tolerances — 43.00 mm inner diameter, 47.00 mm outer diameter, 15.00 mm height, 2.00 mm wall thickness — ensure a direct, rattle-free drop-in replacement.
• Complete renewal in a single kit: two slide bushes replace the full complement of front fork guide bushes in one service.
• Part number GBS-019 guarantees exact fitment accountability when ordering or referencing K-Tech service records.

All-Day Performance and Ride Comfort

When fork slide bushes wear, the damper rod loses its precise lateral support, and small imperfections translate into a vague, tiring steering feel over the course of a long ride or race session. The K-Tech GBS-019 kit addresses this directly. The PTFE interface layer allows the inner and outer tubes to glide against one another without the stick-slip behaviour that causes harshness over small bumps, so the fork tracks the road or track surface faithfully and without interruption.

The copper coating on the hardened steel body provides a dual benefit: it acts as a sacrificial anti-corrosion layer that protects the steel substrate through seasons of road use, and it helps the bush bed in smoothly during initial installation. The result is a fork that feels noticeably more planted and communicative, reducing rider fatigue on extended outings and improving confidence under braking and mid-corner.

Build Quality and Materials

K-Tech manufactures the GBS-019 to the same dimensional standards used in their race-specification suspension rebuilds. Each bush is turned from hardened steel to close tolerances before the copper plating and PTFE surface treatment are applied. This multi-layer approach means the component is neither too tight nor too loose in the fork leg — it supports the sliding surfaces properly without introducing unnecessary resistance, which would dull the suspension response.

Fitment and Compatibility

This kit is specifically designed for and compatible with the following model:

• Honda CBR 1000 RR-R / SP — SC82 chassis — model years 2020 to 2026

Do not attempt to fit GBS-019 to other models or earlier SC59/SC77 chassis variants. If you are unsure whether this kit suits your specific build, confirm the frame code before ordering.

Installation requires specialist tools and fork assembly knowledge. K-Tech recommends having the bushes fitted by an authorised K-Tech Service Centre to ensure correct press-fit depth, proper alignment, and the sustained chassis performance the kit is designed to deliver.
