VForce4R reed box KTM SX 85/105 03-19 / Husqvarna TC 85 14-19

New V-Force 4 carbon reed box, replaces the V-Force 3. They increase low downforce considerably, with the end result of getting more power out of your bike.

The new VForce4R reed box for the KTM SX 85 / SX105 2003-2019 and Husqvarna TC 85 2014-2019 has been designed to offer exceptional durability and significantly improve the performance of the stock reed system.

Unique VForce reed valve system design 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.

This Moto Tassinari V-Force intake reed system features a patented, state-of-the-art diaphragm 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.
