Reed Valve Malossi MHR VL14 Yamaha Aerox / MBK Nitro

Malossi MHR Reed Valve "VL14" Piaggio NRG / Typhoon, one of the best reed valves on the market.

It comes with a Venturi stuffer, but without stops. Ideally suited for tuned and racing engines.

The vulcanized rubber surface has excellent sealing properties to prevent backwash and low crankcase pressure. The Venturi stuffer will optimize flow and improve cylinder filling and performance.

For even higher performance, we recommend placing a 5mm spacer underneath the reed block. The spacer, by adding 5mm, pulls the tips of the petals back out of the flow and increases intake tract length which in turn will result in improved performance at high rpm.
