Description
V-Force 4 Reed Valve by Moto Tassinari from Stage6
Tuning specialist Stage6 has expanded its already extensive product catalog with another standout addition: the Stage6 V-Force 4 Reed Valve by Moto Tassinari, designed for CR85/Derbi engines.
Originally developed for the Motocross Honda CR 85, the V-Force 4 reed valve can also be installed on original Derbi Euro 2 / Euro 3 / Euro 4 engine cases. However, the crankcase must be slightly modified on both sides to accommodate the installation.
Who is the V-Force 4 for?
The V-Force 4 by Moto Tassinari is designed for ambitious tuners and motorsport enthusiasts looking to maximize the performance of their Derbi engine. With its high-end performance and meticulously engineered upgrades, this reed valve takes your machine to the next level.
Compared to the V-Force 3, the V-Force 4 offers innovative features and enhancements that significantly boost the performance of your racing engine. Designed with a dual reed system, it delivers improved air-fuel flow, resulting in better torque, acceleration, and overall performance across the entire RPM range. While the V-Force 3 is already an excellent product, the new V-Force 4 sets an even higher standard, firmly positioning itself as a high-end option.
Improvements and Benefits of the V-Force 4
- Optimized reed petals: Pre-shaped petals provide better sealing and increased efficiency.
- Enhanced carbon fiber construction: Improves durability and performance of the reed petals.
- Larger airflow capacity: A wider reed cage and a 10.5% larger reed surface area for enhanced flow.
