KTM 85 2003 - 2020 Moto Tassinari Vforce 4R Reed Valve. SKU: E07KT080019 MPN: MT-V4R85A KTM 85 KTM 105. The unique design of the VForce reed valve system features double the reed tip surface over a conventional reed valve design.
This has two major benefits. The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. Because the reed petals only need to travel half the distance of that on a conventional reed valve design, there is a greater chance of them being fully opened as well as a better chance of sealing when they are "closed".
A reed petal never truly "closes" in a classic sense, as it is always in movement. Consider this, an engine operating at 8,000 RPM results in a reed petal opening and closing 133 times in one second.This fact, sheds light on another VForce advantage. Since the petals are only traveling half the distance, they generally last longer as they receive less wear than the reed petals on a conventional reed valve design. Conventional reed valve design Increased torque at bottom end, stronger mid-range and longer top-end Greater efficiency due to less reed petal travel More airflow means greater horsepower Longer reed petal Life Screw free design ensures easy petal replacement. IMPROVED VFORCE4 FEATURES New design reed petal resin system, carbon fiber and lay-up Pre-curved reed petal gives better seal at tip Wider reed cage design for maximum airflow Combined reed tip area increased by 10.5% resulting in greater total air flow Airfoil shape design to cage tip to increase air velocity from outer ports Long reed stops in addition to to progressively slow petal tip velocity, for increased petal durability Reduced frontal area of central wing by 15.6% in addition to a more aerodynamic shape.
ALL-NEW VFORCE4R FEATURES Rubber overmodling on reed tip surface of cage to even more petal life Extended reed petal stops Pre-curved reed petal ensures better seal at tip.
