Stage6 R/T Viton® Reed Valve - Aerox/ Minarelli


Add to Basket

Stage6 R/T Viton® reed valve for Yamaha Aerox/ Minarelli 50cc 2-stroke horizontal engines.

This high performance vulcanised Stage 6 reed block complements your Stage6 setup and is ideally suited to 70cc cylinders or if you have a 19 mm carb or higher.

The reed valve is made of fuel-resistant Viton® and comes with 0.35mm Stage6 carbon reeds, 0.4mm fibreglass reeds and three stuffers (24, 26 and 28mm).

For Minarelli, an additional 4mm spacer is included. It will be mounted under the reed valve to raise the reeds and thus ensure that sufficient fresh charge is directed towards the boost port.
