Original Piaggio, modified cylinder to allow the power of 180ccm even on the smaller engines! Absolutely inconspicuous because of the Piaggio marking on the outside of the cylinder (important e.g. for Dragster). In combination with a sport exhaust, the higher compression Malossi cylinder head and the 25mm carburettor kit, it offers a strong performance increase which helps a dragster to over 150 km/h (speedo) with a longer gearbox. For Mikuni carburettor use 97,5 main jet. Cylinder 180cm³ Piaggio - Gilera (suitable for 125-150ccm engines - d.70mm)
