New V-Force 4 carbon reed box, replacing the V-Force 3. They increase the low end considerably, with the end result of getting more power out of your bike.
The new reed boxVForce4Rreed box for theYamaha YZ85 1993-2020has been designed to offer exceptional durability and significantly improved performance over the stock reed system.
Unique VForce reed valve system design features twice the reed tip surface area 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.
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 one found on the stock bikes, as the blades offer twice the surface area, so they travel half the distance and the same airflow and fuel flow is achieved.
The combination results in explosive acceleration, improved throttle response and better fuel efficiency.
