A friend of mine has a liquid-cooled Piaggio which he is going to tune and he wonders what is the most powerful cylinder for his scooter. Please come with your best tips....
if you friend plans on using the bike as a street bike then go with the polini evo set with a malossi over range trans. if he just plans on using it as a race bike then go with the Hebo Manston, try something new.
I know the Malossi Mhr cylinders are really powerful but i know that the MK Prorace 2 cylinder is powerful too. It has alot to do with the rest of the setup too......
