Description
VForce4R reed box for Honda CR80 / CR85 1980 - 2007.
Designed to significantly increase power at low revs, with the end result being more power output.
Unique VForce reed valve systemdesign features twice the reed tip surface area over a conventional reed valve design.
Key Features
- The reed petals only travel half the distance as a conventional reed valve design to achieve the same airflow.
- Because the reed petals only need to travel half the distance as a conventional reed valve design, there is a greater chance that they will open fully, as well as a better chance of sealing when "closed", giving more horsepower, and a noticeable change to gas response. Being fitted by many Origin brand manufacturers.
Additional information: It is possible to fit this reed box on Derbi Euro 2 / 3 / 4 / 5 engines by making some modifications to the crankcase
