The VFORCE/Moto Tassinari V-Force 4 Reed Valve Set is a performance intake upgrade for 2-stroke engines, designed to increase airflow and improve reed life. Pre-curved carbon fiber petals help seal better for crisp response and consistent running.
The VFORCE/Moto Tassinari V-Force 4 Reed Valve Set is built to help your 2-stroke engine breathe more efficiently while improving long-term durability. With a wider reed cage and an updated airflow-focused design, it supports stronger intake flow and sharper throttle response—ideal when you want reliable performance on track or trail.
This reed valve assembly also addresses a common problem with high-performance 2-strokes: reed wear and loss of sealing over time. Pre-curved carbon fiber petals promote a better seal at the tip, while long reed stops progressively slow petal tip velocity to reduce stress and extend petal life. Rubber overmolding on the reed-tip contact surface further helps protect the reeds during repeated cycles.
