{"product_id":"v-force-4-reed-valve-system","title":"V-Force 4 Reed Valve System","description":"The Moto Tassinari V-Force 4 is an advanced reed valve system engineered as a complete redesign of the previous VForce3 platform. By doubling the reed tip surface, the petals travel only half the distance of conventional designs to achieve the same airflow, which improves both responsiveness and sealing performance. The system incorporates an all-new carbon fiber reed petal resin system and a wider cage to maximize total airflow. Additional features include an airfoil shape on the cage tip to increase air velocity from the outer ports and long reed stops to slow petal tip velocity, enhancing overall component durability.\n\nInstallation for Yamaha RD250, RD350, and RD400 models requires specific modification of the cylinder intake ports. Although the bolt pattern is compatible, the valve will not slide in without material removal on the intake port walls. Owners without the ability to perform these modifications should not purchase this system for those specific models. The package includes two complete reed valve assemblies, gaskets, decals, and detailed installation instructions.\n\nThis system is explicitly designed for the Yamaha YFZ350 Banshee (all model years) and requires no modifications for those specific applications. The screw-free construction eliminates the risk of loose fasteners entering the engine while allowing for rapid reed petal replacement.","brand":"Moto Tassinari","offers":[{"title":"Default Title","offer_id":52663049322808,"sku":"V4144-2","price":202.46,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687512421.jpg?v=1784323221","url":"https:\/\/store.motormia.co\/products\/v-force-4-reed-valve-system","provider":"MOTORMIA","version":"1.0","type":"link"}
