VFORCE/MOTO TASSINARI V-Force 4 Reed V4R01D

The Moto Tassinari V-Force 4 Reed V4R01D delivers measurable improvements in port velocity and petal durability—critical factors for engines operating at high RPM where reed failure directly impacts reliability and power output. The extended reed stops progressively decelerate petal tip speed, reducing stress on the carbon-fiber composite material and extending service life between rebuilds. With a 10.5% increase in combined reed tip area and refined airfoil engineering, this reed cage maximizes flow efficiency across the intake cycle.
