Here are the Top Performances Racing TPR valves, the Top Performances brand has succeeded in developing a valve box from V Force type 3 (the best of all in 2-stroke competition) reviewed and corrected. It will offer you maximum acceleration and torque while maintaining a really excellent peak, there is no competition on the market for such a price.
8 slats including 4 inside, all in high-end carbon, recommended with a carburation of Ø19mm to 26mm, it is also supplied with a diffuser (venturi) in d.26mm which will allow you not to lose gas diffusion.
Same aesthetic level it is really successful. The v.force system makes it possible to obtain 2 distinct resonance frequencies, one at low speed and one at high speed! The must however has a price but with such equipment, you are sure of what to buy.
This system is already very famous in 125/250cc 2-stroke cross competition. We regret that other more rigid slats are not provided and are not available in pre-cut on the market!
