DescriptionThe whole story▼
Smooth, consistent fork action is the foundation of all-day riding comfort — and over thousands of kilometres, worn slide bushes are the silent culprit behind vague steering and a harsh, unpredictable ride. The K-Tech GBS-007 fork slide bush kit is engineered specifically for the Kawasaki ZX-6R, ZX-636 and ZX-6RR from 2005 to 2026, restoring that original plush precision and keeping it there for the long haul.
Key Features
- Direct OEM replacement: designed exclusively for the Kawasaki ZX-6R, ZX-636 and ZX-6RR (2005–2026) for a perfect, hassle-free fitment every time.
- Hardened steel construction with a copper undercoat delivers outstanding resistance to wear, maintaining dimensional accuracy even under sustained load and repeated fork cycling.
- PTFE-coated contact surfaces minimise friction throughout the full stroke, giving the fork a noticeably smoother, more compliant action on both road and track.
- Reduced stiction means the fork responds to small-bump inputs that a worn or standard bush would absorb, improving rider feel and reducing fatigue over long rides.
- Complete kit: two slide bushes supplied, covering both fork legs in a single purchase.
Build Quality & Performance
K-Tech has built its reputation supplying suspension components to World Superbike and British Superbike teams, and that same engineering rigour goes into every GBS-007 kit. The hardened steel shell provides the structural backbone, the copper layer bonds the PTFE coating for long-term adhesion, and the PTFE face itself acts as a self-lubricating bearing surface. The result is a bush that runs cooler, lasts longer, and keeps the fork tracking true — qualities that matter as much on a long motorway run as they do in a tight chicane.
Road & Track Use
Whether you are covering daily commutes on a ZX-6R, touring on a ZX-636, or turning laps on a ZX-6RR, degraded slide bushes translate directly into arm-pump, reduced confidence in corners, and a bike that feels older than it should. Swapping to the GBS-007 kit is one of the most cost-effective suspension refreshes available: the geometry stays stock, but the feel becomes markedly more precise and fatigue-free across an entire day in the saddle.
