Moto Tassinari . V417A

Moto Tassinari V-Force 4 Reed Valve System ; 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 super quick reed petal changes ; NEW AND IMPROVED VFORCE4 FEATURES - All-new reed petal resin system, carbon fiber and lay-up - Pre-curved reed petal ensures better seal at tip - Wider reed cage for maximum airflow - Combined reed tip area increased by 10.5% resulting in increased total air flow - Airfoil shape added to cage tip to increase air velocity from outer ports - Long reed stops added to progressively slow petal tip velocity, for increased petal durability - Reduced frontal area of central wing by 15.6% combined with a more aerodynamic shape ; Fits on: KTM *250SX ;2003 *250/300 EXC/MXC ;2004 to 2006 250SX ;2004 to 2015 250/300 EXC/MXC ;2007 to 2015 ; *REQUIRES 2004 250 SX INTAKE BOOT
