All NTR TVT Cartridge Kits feature large bore 25mm pistons which provide significant improvements in performance over the OEM set up and ensure consistency during prolonged periods of use. All vital components are hard anodized with the option to upgrade to ‘Pro’ specification which includes ultra-low friction Kashima coating if desired.

Developed and tested in conjunction with some of the world’s leading race teams, independent adjustment control of rebound and compression damping is both easy to use and extremely effective. The damping control system consists of an adjustable compression cartridge for installation into the left fork leg and an adjustable rebound cartridge for the right fork leg. Both offer independent damping and pre-load adjustment via the uniquely styled fork top caps.

In addition, what really sets the TVT Fork Cartridge Kits head and shoulders above the competition is the fully integral Tri-Valve Technology system. By incorporating the TVT high speed damping valve into the compression cartridge, Nitron has been able to achieve the ultimate balance of performance, stability and compliance which provides unrivalled levels of rider confidence and control. All three valve pistons can be quickly and easily removed for re-valving without the need to remove the forks from the bike, keeping workshop time to a minimum and meaning trackside changes and set-up can be done with ease.
