Exhaust Malossi -MHR- for the water-cooled Piaggio/Gilera 125/180cc engines. Designed for the 172cc Malossi cylinder, but of course can also be used on ported original cylinder. has a short resonance length and should therefore not be driven with too much exhaust head angle. Otherwise, the starting torque quickly collapses.
Fits e.g. Gilera Runner 125-180, Italjet Dragster 125-180. Not suitable on the air-cooled engines (manifold comes to fan wheel cover).AI-translation
