Stage6 R/T FKM (Viton®) reed valve for Minarelli AM6 and Derbi EBE, EBS, D50B0 and D50B1 engines. Its two-petal design supports improved cylinder filling.

The vulcanized reed block complements Stage6 setups and is suited to carburettors of 19 mm and larger. Its Viton®/FKM coating provides a well-sealed intake and increased resistance to hydrocarbons.

Includes two petal sets: 0.35 mm carbon petals for high-performance setups and 0.40 mm glass-fibre petals for racing engines. Malossi and Polini intake manifolds are recommended for close alignment with the reed block’s stuffer.

Suitable for Derbi Euro 2 and Euro 3 engines. For Minarelli AM6 installation, the crankcase must be machined 0.5 mm on both sides of the reed valve.

In the box : Stage6 R/T reed valve with petrol-resistant Viton®, one set of 0.35 mm carbon petals, one set of 0.40 mm glass-fibre petals, and a venturi insert/stuffer.
