Product details
Les boites clapets VForce de Moto Tassinari sont une référence pour les spécialistes de la préparation des moteurs 2 temps depuis plus de 10 ans. Les boites à clapets VForce4Ri permettent d’augmenter la puissance du moteur et la réactivité des gaz, grâce à l’amélioration de l’efficacité du système d’admission par rapport aux clapets d’origine.
Caractéristiques Vforce standard :
- Double the contact surface compared to original valves
- Increases performance across the entire engine speed range: low speed, mid-speed, and high speed
- More efficient system thanks to stiffer valves
- Increased airflow = increased power
- Highly resistant valves, reduced wear
- Screwless construction: reduced risks and quick valve changes
Vforce4 features:
- New carbon fiber valves
- Pre-curved valves ensuring better sealing
- Larger valve box for improved air circulation
- Combined valve tail increased by 10.5% to promote and increase overall airflow
- Aerodynamic profile at the end of the box to increase the air speed of the external intake ports
- Longer valve stop to gradually reduce speed at the end, for longer service life
- Front area of the central lamella reduced by 15.6% combined with a more aerodynamic profile
Spécificités Vforce4Ri :
- Rubber overmolded on the surface of the valve tips to increase the service life of the intake valves
- Manifold, valve box, and air deflector are specially designed for the VFVorce4R system.
- Venturi conçu spécifiquement pour améliorer le flux du mélange et donc les performances
