DescriptionThe whole story▼
Precision-engineered for the Honda CBR 600 RR across every model year from 2005 to 2025, the K-Tech GBS-007 fork slide bush kit is the benchmark replacement for riders who will not compromise on front-end safety and feel. Manufactured to exacting tolerances, these bushes restore correct fork alignment and smooth travel — fundamentals that underpin both chassis stability and rider confidence at any speed.
Key Features
- Exact-fit replacement for the Honda CBR 600 RR (2005–2025), covering two decades of production without modification
- Hardened steel construction with a copper coating for superior wear resistance and long service life
- PTFE-coated contact surfaces minimise friction throughout the fork stroke, resulting in smoother, more responsive front suspension
- Tighter tolerances compared to OEM specifications reduce fork flex and improve steering precision
- Supplied as a pair — both fork legs are replaced simultaneously for consistent, balanced performance
- Professional installation at an authorised K-Tech Service Centre is strongly recommended; specialist tooling and techniques are required to ensure safe assembly
Engineering & Materials
The GBS-007 slide bush starts with a hardened steel substrate that resists deformation under the cyclic loading a fork bush experiences on both road and track. A copper inter-layer improves thermal conductivity and acts as a sacrificial wear surface, protecting the harder steel during the initial bedding-in period. The inner contact face carries a PTFE coating — the same low-friction material used across high-end suspension components — which dramatically reduces stiction and allows the fork to respond to small-amplitude bumps that an inferior bush would simply filter out as deadband.
The result is a front end that tracks more accurately under braking, holds its line through corners, and transmits meaningful feedback to the rider rather than a vague, over-damped sensation.
Performance on Road and Track
Worn or degraded fork bushes are one of the most overlooked causes of vague steering on a CBR 600 RR. Replacing them with K-Tech GBS-007 units restores the geometric precision the chassis was designed around. On the road this translates to relaxed, predictable handling; on track it gives the confidence to brake deeper and carry more corner speed without the front end feeling loose or unpredictable.
Fitment & Compatibility
This kit fits the Honda CBR 600 RR (PC37 and PC40 chassis) across all model years from 2005 to 2025. It is not compatible with other models or variants. Always confirm your fork inner tube diameter before installation.
