Product details
The VF4 builds on the VF3 with a series of upgrades aimed at better performance. Carbon fibre reed petals paired with a new resin frame raise airflow by 10% over the standard system, improving velocity and performance. The VForce4 also has external walls that shield the reed petals, helping them last longer.
How the VForce design works
Compared with a conventional reed valve, the VForce system has twice the reed-tip surface area. That brings two main advantages:
- Less petal travel: to move the same volume of air, the petals only have to travel half as far as in a conventional system.
- Better performance and longer life: with less distance to cover, the petals are more likely to open fully and to seal properly when "closed". Reed petals are always moving, so they never close completely, but the smaller movement in the VForce system cuts wear and extends their life.
To put it in perspective, a reed petal at 8,000 RPM opens and closes 133 times every second. Reducing its travel greatly reduces the stress and wear it has to deal with.
Standard VForce features
- Twice the reed-tip surface of conventional designs
- More bottom-end power, a stronger mid-range and a longer-reaching top end
- Better efficiency thanks to shorter reed petal travel
- Greater airflow for more horsepower
- Less reed petal wear
- Screw-free design, so there is no chance of screws getting into the motor
- The screw-free design also makes reed petal changes quick and easy
VF4 upgrades
- All-new resin reed petal system using carbon fibre with an optimised lay-up
- Pre-curved petals that seal better at their tips
- A wider reed cage gives maximum airflow
- Combined reed tip area up by 10.5% for greater overall airflow
- Airfoil-shaped cage tips that speed up the air coming from the outer ports
- Long reed stops that gradually slow the petal tips, improving durability
- Central wing frontal area cut by 15.6%, with a more aerodynamic shape
