DescriptionThe whole story▼
Unlock the full potential of your Kawasaki ZX-6R's stock forks without the cost of a full replacement. The K-Tech 25IDS Open Cartridge Kit gives everyday riders and weekend track enthusiasts alike a meaningful, accessible upgrade — precise, independent damping adjustment that transforms how the ZX-6R responds to real-world road conditions across the entire 2009–2019 model range.
Key Features
- 25mm Independent Damping System (25IDS) engineered specifically for the original ZX-6R fork internals, ensuring a direct, no-compromise fit
- 24 clicks of independent compression adjustment and 30 clicks of independent rebound adjustment for fine-grained, rider-specific setup
- 18 mm of spring preload adjustment to dial in ride height and balance for your weight and riding style
- Increased stroke over the stock cartridge delivers improved suspension travel and better small-bump compliance on public roads
- Hard-anodised, super-finished aerospace-grade aluminium construction for exceptional wear resistance and long service life
- Suggested baseline settings included (12 clicks compression, 18 clicks rebound, 8 mm preload) so you can ride confidently from day one
Built for Real Riding, Ready for the Track
The 25IDS system separates compression and rebound circuits completely, meaning adjustments made to one have no influence on the other. This independence is what separates a genuinely tuneable cartridge from a compromise — you can soften the rebound for a more planted feel on rough tarmac without inadvertently affecting how the fork handles braking forces. For a ZX-6R used on both road and circuit, that flexibility is invaluable.
All components are manufactured from aerospace-grade aluminium and subjected to a hard-anodising process followed by a super-finish surface treatment. The result is a cartridge that resists wear over thousands of miles, maintains consistent damping characteristics, and requires far less maintenance than softer-finished alternatives.
Installation & Setup Guidance
K-Tech recommends installation by an authorised K-Tech Service Centre to ensure correct assembly, oil fill, and initial setup. The suggested starting clicks — 12 compression, 18 rebound, 8 mm preload — give a sensible baseline that works well for a range of rider weights and road conditions, making it straightforward to begin refining from there. Please note that matching fork springs must be ordered separately; consult the K-Tech 36-260 spring series for compatible options.
