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. Rubber overmodling on reed tip surface of cage to further enhance petal life.
All-new manifold, reed cage and air guide designed for the VFVorce4R. 2018-20 KTM 300 EXC TPI. 2018-20 KTM 250 EXC TPI.
