New carbon reeds box V-Force 4, which replaces the V-Force 3. They increase considerably at low revs, resulting in more output power for your bike.

The new reeds box VForce 4R has been designed to offer exceptional durability and significantly improve the performance of the original reeds system.

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

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

2) Because the reed petals only need to travel half the distance as in a conventional reed valve design, there is a greater chance they will open fully, as well as a better chance of sealing when "closed", resulting in more horsepower and a noticeable change in throttle response.

This V-Force intake reeds system from Moto Tassinari features a patented and cutting-edge membrane valve design.

The design accelerates the air flow mixture to deliver more horsepower to the engine with a noticeable improvement in throttle response, and a significant increase in the bike's performance.

This design has more advantages than the stock bikes, as the reeds offer a surface area twice as large so they travel half the distance and achieve the same airflow and fuel flow.
