V-Force 2005-2008 Honda CR125 Reed Valve Kit V321A
The Moto Tassinari VForce system has won countless championships and is the reed valve of choice for Amateur as well as seasoned dirt bike riders. Ricky Carmichael and James Stewart, to name a few, put these reeds to the test and submitted it to the hardest riding style and getting championship results. For most people the first step to 2 stroke reed valve tuning is getting rid of that OEM reed valve and replacing it with the Vforce Reed valve system. The Vforce Reed has a snap together cage using symmetrical reed petals, eliminating the need for different inner and outer replacement petals.
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.
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.
