Reed Valve Yamaha Blaster V-Force 4

V-Force 4 carbon reed valves, which replace the V-Force 3. They increase considerably in lows, with the end result of obtaining more power output from your motorcycle.

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

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

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

2) Because reed petals only need to travel half the distance than in a conventional reed valve design, there is a greater chance that they will fully open, as well as a better opportunity to seal when closed, achieving more horsepower and a noticeable change in gas response.

This Moto Tassinari V-Force intake plate system features a state-of-the-art patented membrane valve design.

The design accelerates airflow mixing to bring more horsepower to the engine with a noticeable improvement in throttle response, and a significant performance boost on the bike.

This design has more advantages than the ones that come from home motorcycles, since the blades offer a surface twice as large, so they travel half the distance and achieve the same air and fuel flow.

The combination results in explosive acceleration, better throttle response, and better fuel economy.

Attention! To adapt it to the Yamaha DT 125 R, the reed box must be modified to match the distance between screws and depending on the year, the crankcase must be filed.
