Yamaha YZ65 (18-25) VForce4Ri Reed Valve Kit MT-V4R82B-I

Moto Tassinari have developed a new Performance Reed Valve for the new Yamaha YZ65 Junior MX dirt bike. The Vforce V4R82B-I has a custom intake manifold boot included that improves airflow and performance. The Vforce 4 Reed block has carbon fibre reed petals designed to give increased performance and longer life with both pump fuel and racing fuel i.e. Roo or ETS.

As with the Vforce 4 reed blocks for Yamaha YZ85 YZ125 and KTM125 the YZ 65 V4R82B-I has a rubber overmolded pad on the reed tip area of the reed cage to greatly improve reed petal life.
