Malossi MHR exhaust for water-cooled Piaggio 125-180cc engines
Malossi -MHR- exhaust for water-cooled Piaggio/Gilera 125/180cc engines. Designed for the 172cc Malossi cylinder, but can of course also be used on ported original cylinders. Has a short resonance length and should therefore not be run with too much exhaust timing angle. Otherwise the starting torque will quickly collapse.
Suitable for e.g. Gilera Runner 125-180, Italjet Dragster 125-180. Not suitable for air-cooled engines (manifold comes on fan wheel cover).
