Moto Tassinari has extracted more power and more performance from our already proven Vforce3 reed valve system design for the 85cc market, by offering the all-new Vforce3i with integrated intake boot (included on CR, RM & YZ models only). the Vforce3i shares many of the same features as it’s legendary big brother, along with these additional unique features

Upgrade the intake performance of your Yamaha YZ65 with the Moto Tassinari VForce4Ri Reed Valve System, manufacturer part number V4R82B-I. Designed specifically for 2018-2022 Yamaha YZ65 models, this reed valve system helps improve fuel and air distribution, throttle response, and overall engine performance. The VForce4Ri design builds on Moto Tassinari’s proven reed valve technology with features engineered for the demands of high-performance 65cc motocross applications.

The system uses a newly designed intake boot with a centralized opening to create a straighter path into the engine cases. This straight-shot design promotes more even fuel and air distribution throughout the engine, while the redesigned reed stops help improve reed petal stability and control the opening movement. A shorter reed cage allows the use of lighter reed petals, helping deliver responsive operation and a noticeable performance increase across the powerband.

Developed for direct integration with compatible Yamaha applications, the Moto Tassinari VForce4Ri provides a purpose-built fit for the YZ65 platform. The assembly is intended as a performance replacement for the original reed valve system and is suited for riders seeking improved intake efficiency and engine response without unnecessary modifications. Verify the motorcycle year and model before installation to ensure proper fitment.
