The MotoForce Racing Evo reed valve features four carbon petals and fits 50cc motorcycles equipped with a Minarelli AM6 or Derbi engine, including models such as the Rieju MRT, Beta 50 RR, Derbi Senda, Gilera SMT and Sherco 50.

Designed for straightforward installation on AM6 and Derbi engines, it uses slotted mounting holes to fit without modifications. Its V-shaped design and Venturi stuffer help improve cylinder filling and throttle response.

A practical upgrade for tuned two-stroke engines, this reed valve is suited to sports and racing setups and can be paired with a PWK carburetor. It has a carefully finished sealing surface and comes with two paper gaskets.
