VFORCE/MOTO TASSINARI V-Force 4 Petal Set 4P522

Reed petals are the gatekeepers of engine efficiency—worn or damaged reeds kill acceleration and cost you power when it matters most. The V-Force 4 Petal Set delivers measurable airflow gains and extended durability through precision engineering, making it the upgrade choice for serious two-stroke competitors and high-performance builders who demand reliability without compromise.

This complete reed set replaces worn petals with a redesigned architecture that prioritizes both flow and longevity. Long reed stops progressively decelerate petal tip velocity, reducing stress and extending service life, while a 10.5% increase in combined reed tip area pushes more air into the combustion chamber.

• Long reed stops reduce petal stress
• 10.5% increased reed tip area
• All-new carbon fiber resin system
• Pre-curved petal design seals consistently
• Aerodynamic central wing reduced frontal area
• Airfoil-shaped cage tips boost velocity
• Wider reed cage maximizes airflow
• One complete set per cage
• Bolt-on replacement, no fabrication required
• MPN: 4P522
