SIP is now offering a 306cc engine for Vespa large frame models. The engine case, cylinder and crankshaft have been redeveloped and adapted resulting in improved power and torque throughout the rev range. A race version of this engines has already made 55hp and it is hoped that 70hp is possible with further fine tuning. The range includes engine upgrades for 125-200cc large frame Vespas, and a 225cc version is available with transfer ports of Malossi cylinder heads.
