Stage6 Viton® reed valve for Yamaha BWS/ Slider 50cc 2-stroke Minarelli Vertical engines.

So-called biofuels are becoming more and more popular. They may, however, contain up to 20% of pure alcohol, which makes the fuel more aggressive towards standard NBR rubber compounds. Over time, the alcohol will soften the NBR. In order to adapt to this trend, Stage6 Development is going to offer future products that are subject to extensive fuel contact (reed valves, intake manifolds etc.) in a FKM (Viton) compound, which will be slightly more expensive, but also more alcohol- and heat-resistant. 

Specifications:
- Reed valve made from petrol-resistant Viton®
- 1-reed design
- Incl. carbon petal 0.35mm
