2019 YZ65/YZ85 VForce4R Reed Valve

Enhance Performance for the 2019 Mini Yamaha Models

VForce4R YZ65 and YZ85

 

Recently, Pro Circuit stocked the new VForce4R reed valve system by Moto Tassinari for the 2019 YZ65/85. Moto Tassinari's VForce4R reed valve system is designed with a shallower petal angle which allows them to open further and with much less force than that of the stock reed system equating to better fuel flow and ultimately more power. The shallower reed petal angle also reduces the tension on the petals resulting in increased strength and durability keeping your minibike rider out on the track longer. Moto Tassinari's VForce4R reed valve system also incorporates an all-new manifold, reed cage and air guide to boost overall performance.

 

Over the years Moto Tassinari has made many upgrades to their VForce reed systems and the VForce4R reed block for the 2019 YZ65/85 is no exception. Pick up a VForce4R reed system at Pro Circuit for your minibike rider and ensure he or she is getting the best performance from their 2019 YZ65 or YZ85.
