STANDARD VFORCE REED VALVE FEATURES

• Double the reed tip surface over a conventional reed valve design
• Increased bottom end, stronger mid-range and longer top-end
• Greater efficiency due to reduced reed petal travel
• More airflow means more horsepower
• Reduced reed petal wear
• Screw free design eliminates risk of screws going through motor
• Screw free design enables rapid reed petal changes

IMPROVED VFORCE4 FEATURES
