Malossi Carbon Reed Petals for Factory Reed Valve on Piaggio / Yamaha 50cc 2T Scooters.
Suitable for many makes and models. Most factory reeds are made from thin steel, which is strong but not very flexible, or forgiving if a small piece splinters off into the crank casing.
Carbon reeds offer far more flexibility for more throttle response. As an added bonus, if failure occurs the carbon will easily burn up inside the cylinder rather than causing issues. Carbon reeds to however need to be replaced more regularly, as they wear out faster than steel.
