TVT FORK CARTRIDGE KIT

  

Nitron are pleased to announce the brand new range of TVT Adjustable Fork Cartridge Kits for the CRF1100 Africa Twin / Adventure Sport.

Developed primarily to compliment and work with Nitron NTR shock upgrades, they 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 25mm piston which provides significant improvements in performance over the OEM set up and ensures consistency during prolonged periods of use. All vital components are hard anodised with the option to specify 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 to this, a key feature of the TVT Fork Cartridge Kit is the third, high speed damping valve incorporated into the compression cartridge. The valve is pre-set to react to high-speed, hard edge bumps which normally unsettle a well damped set up especially when combined with hard braking and cornering forces. The result is a balance of performance, stability and compliance which give very high levels of rider confidence and ultimate 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.

In motorsport, SuperBike riders have praised the ability of the TVT cartridges as they have felt confidence increase to new levels and lap times tumble. Probably just as impressive as the on track ability is just how adaptable the Tri-Valve Technology is for road use, giving all levels of rider the confidence to make adjustments to achieve a more usable and more capable bike.

DETAILS

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 25mm 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 17mm hex with each complete turn of the adjuster resulting in 1mm of additional spring preload from a total of 18 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.

In addition to the main piston in the compression leg TVT cartridges also employ a third piston which gives a great deal of flexibility when designing the damping curve for a specific application. This piston also utilizes shims in much the same way as the main compression piston but with this design the shim stack is preloaded. During slow to medium speed movements of the fork in compression such as braking or through undulations in the road the damping is created by the main piston. As the pressure in the compression cartridge reaches a certain point the preload on the second piston will be overcome and oil can now flow through the TVT ports reducing overall damping for the higher fork speeds.

 

Fork_Travel_Speed

 

The main piston in a TVT fork cartridge can be valved to create firmer damping in the low to mid speed range of compression velocities giving improved brake support and control of weight transfer leading to improved rider confidence. With a single compression piston design this would normally result in unwanted high speed damping forces being generated at higher compression velocities such as square edged bumps and surface irregularities.

On track, professional riders have praised the system describing new found levels of confidence particularly during high speed , hard edge bumps which combined with hard braking and cornering forces would normally unsettle a well damped set up. Likewise on the road this system has allowed new levels of compliance on bumpy poorly surfaced roads.

The TVT valve has also been designed to allow quick and easy re-valving and can be extracted from the fork without having to remove the forks from the bike.
