Brand: V-FORCE — Product: V‑FORCE4 Reed Valve Box for Yamaha YFZ 350 BANSHEE

Based on the proven design of the V‑FORCE3, the V‑FORCE4 brings a targeted evolution of the intake system for YFZ 350 Banshee quads. The carbon fiber reeds, combined with a reworked resin frame, provide an optimized airflow approximately 10% greater than the original setup, resulting in improved machine velocity and a more responsive intake reaction.

The housing features external walls covering the reeds to protect them from debris and impacts, thus contributing to the longevity of the entire assembly. Composite materials and careful reinforcements ensure good durability in demanding off-road use.
