Description

The Moto Tassinari V-Force 4R V4R26H is a reed valve system designed to enhance performance for select KTM, Husqvarna, and GasGas 125cc, 150cc, and 250cc carbureted models. This 'H' version features a higher tension reed petal for increased performance and durability in higher-revving engines. The design doubles the reed tip surface area compared to conventional systems, leading to increased airflow, stronger mid-range, and a longer top-end. It also offers greater efficiency due to reduced reed petal travel and a screw-free design for enhanced durability and easier maintenance.
