Suitable for fitment to most large frame Vespa scooters, these Pinasco 251cc motor kits, are available in either standard rotary valve induction, or reed valve induction, and will bring a new level of power to an old scooter. Even though they are tuned to be an easy smooth ride with plenty of low down torque Pinasco are quoting 30bhp from the reed valve version when used with a 30mm carb.  https://ve-uk.com/classic-vespa-search/?search=true&listid=6&makeid=136&modelid=1708&groupid=87]]>
