VForce4 reeds box Yamaha RD 350 / Banshee - 2 units

2 boxes of reeds V-FORCE 4 for Yamaha RD and Banshee 350cc

In Vespa this box is compatible with the MRP reed boxes.

New carbon reed 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 reed box VForce 4R has been designed to offer exceptional durability and significantly improve the performance of the original reed system.

Unique design of the VForce reed valve system features double the reed 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 that they open fully, as well as a better chance of sealing when they are "closed", resulting in more horsepower and a noticeable improvement in throttle response.

This V-Force intake reed system from Moto Tassinari features a patented, 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.
