DescriptionThe whole story▼
Engineered specifically for the Ducati Panigale V4 R, the K-Tech GBS-019 slide bush kit is a direct, precision-fit replacement for the factory fork guide bushes — combining hardened steel construction with a copper underlay and a low-friction PTFE contact surface to deliver noticeably smoother, more consistent fork action from the first ride.
Key Features
- Hardened steel body with copper coating for outstanding resistance to wear and corrosion over extended service intervals
- PTFE-lined contact surface dramatically reduces sliding friction, preserving damping consistency lap after lap
- Exact OEM dimensions ensure a drop-in replacement with no modification required
- Supplied as a complete pair — everything needed for a full fork service in one part number
- Developed by K-Tech Suspension, a name synonymous with championship-level fork and shock technology
Design, Finish and Heritage
K-Tech has built its reputation at the sharp end of World Superbike and BSB, and that heritage is evident in every detail of the GBS-019. The copper-plated steel shell is not an afterthought — it acts as both a sacrificial corrosion barrier and a compliant layer that beds in evenly against the fork tube, eliminating the micro-play that can make a well-worn set of OEM bushes feel vague on turn-in. The PTFE contact face carries that philosophy further, keeping stiction to an absolute minimum so the fork tracks surface changes rather than skipping over them. The finish is purposeful and precise, exactly what you would expect from a company that supplies suspension components to professional race teams.
Performance on Road and Track
On the Panigale V4 R — a motorcycle built around circuit performance — fork feel is everything. Worn or corroded guide bushes introduce lateral play into the lower leg, blurring the feedback the rider relies on to place the bike with confidence into a late braking zone. Replacing them with the GBS-019 restores the fork's designed geometry and allows the cartridge internals to work as intended, giving the suspension setup a clean baseline from which K-Tech or authorised technicians can fine-tune compression and rebound with confidence.
