Boite à clapets V-FORCE V-Force 4R - KTM/Husqvarna

Product details

Moto Tassinari's VForce reed valves have been the benchmark for 2-stroke engine tuning specialists for over 10 years. VForce4R reed valves increase engine power and throttle response by improving the efficiency of the intake system compared to the original reed valves.

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

Vforce4R Specifications:

• 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.
