  • MOTO TASSINARI REED VALVE VFORCE 3 V FORCE 3 V FORCE 3 YAMAHA YZ125 95-04 V302A

    The VForce reed valve system by Moto Tassinari has been the reed valve system of choice by anyone serious about two-stroke engine performance for the last 10+ years. The simple premise of the VForce3 reed valve system is to increase engine power and throttle response by increasing the efficiency over a conventional reed valve design. 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 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: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) 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 operatin...

    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: 1) The reed petals only travel half the distance as a conventional reed valve design to get the same airflow. 2) 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 are they receive less wear than the reed petals on a conventional reed valve design.

  • Vforce Reed Valve and Keepitroostin Sticker Fits Yamaha Yz125 1995-2004

    The VForce3 reed valve system by Moto Tassinari incorporates features you won't find with other system on the market. With such features as twice the reed tip surface, radius cage surface and more. By doubling the reed tip surface (over a stock standard valve design) the petals now only need to open half as far to provide the same flow as a stock style cage. This is a significant advantage when you factor in that a reed petal opens and closes 133 times per second at 8,000 rpm. The petals are only traveling half the distance of a stock style cage, so now fatigue to the petal has been greatly reduced, increasing petal life.
