Minarelli vertical carbon sheets 0.35mm Polini

Reeds carbon POLINI 0.35mm, MBK Booster - Stunt / Yamaha BW's - Slider Minarelli Vertical

These reeds replace the reeds of the original reed box.
The carbon reeds allow you to modify the characteristics of the engine.
With thin reeds, the engine pulls more. With thick reeds, the engine works better at a higher number of revolutions.
Another advantage: in case of breakage, steel reeds can end up destroying the cylinder, whereas with carbon reeds it is much more difficult for this to happen.
