Introduction

Introduction

Thank you for purchasing a set of Nitron TVT Fork Cartridges. Nitron have invested 
heavily in developing the technology, materials and performance of our suspension 
components and we are pleased to be able to pass on this experience to our customers. All of our designs 
are based on many hours of both real world testing and racing experience.  TVT technology has proven to 
be extremely versatile and whether you are riding a Superbike on track or adventuring off-road with a Dual 
Sport machine you can be sure that your fork cartridge kit has been developed specifically for your needs.

Nitron TVT Adjustable Fork Cartridge Kits offer the same level of improvements in rider control, 
performance and comfort that have become the trademark of the Nitron product. The system features a 
large bore 22mm shimmed piston which provides significant 
improvements in performance over the OEM set up. 

Function

The damping system is divided between each fork leg with the right hand side cartridge controlling the 
rebound phase and the left hand side compression. This system allows completely independent damping 
adjustment making setup both simpler and quicker. Re-valving is also much quicker particularly when a 
change is only required to one side of the damping curve. 

For ease of use all adjustments are made from the top of the fork, preload is adjusted via a 14mm hex with 
each complete turn of the adjuster resulting in 1mm of additional spring preload from a total of 15 turns. 
Damping adjustment is adjusted using the supplied tool by turning the 3mm hex in the centre of the fork cap, 
there should be at least 25 clicks of adjustment. Careful attention to the design of the adjustment system 
results in not only a broad range of adjustment but the click by click adjustment across the range is very 
linear making a setup easier.
