Stage6 VForce 3I Reed Valve (Honda CR85 / Derbi)

The Stage6 VForce 3i by Moto Tassinari is a high-performance reed valve system designed to provide better crankcase filling and significantly improved throttle response.

Initially developed for Honda CR80 / CR85 engines, it is also very popular on Derbi engines as well as several high-performance setups using Malossi C-One, RC-One crankcases, and some 2Fast engines.

Thanks to its VForce 3i architecture and carbon reeds, this reed valve system improves intake flow, increases low-end torque, and provides sharper acceleration throughout the entire operating range.
