Reed box VForce3 Moto Tassinari Yamaha YZ 125 95-04

A unique V-design engineered for maximum engine performance.
The reed box has twice the surface area with a shorter reed path, improving gas flow and engine response.
Increases performance especially at low to medium RPM.

Applications:kTM 85SX / 105SX
Years:all

Unique design of the VForce reed valve system features twice the surface area of the reed tip over a conventional reed valve design. This has two main benefits:

1) The reed petals only travel half the distance as a conventional reed valve design to obtain the same airflow.

2) Because the reed petals only need to travel half the distance as a conventional reed valve design, there is a greater chance of them opening fully, as well as a better chance of sealing when "closed", making more horsepower, and a noticeable change to gas response. Being fitted by many Origin brand manufacturers.

This Moto Tassinari V-Force intake reed system features a patented, state-of-the-art membrane valve design.
The design accelerates the airflow mixture to bring more horsepower to the engine with a noticeable improvement to throttle response, and a significant increase in performance on the bike.
This design has more advantages than the stock design, as the reeds offer twice the surface area, so they travel half the distance and achieve the same air and fuel flow.
The combination results in explosive acceleration, better throttle response and improved fuel efficiency.
