Vespa makes its fastest scooter a little more zippy with the debut of its GTS 300 Super. The replacement model for the GTS 250, the new Italian ‘wasp’ packs a bigger sting, upping displacement to 278cc. The latest generation of the 4-stroke, 4-valve Quasar (QUArter liter Smooth Augmented Range) Single remains liquid-cooled and fuel injected. A 75mm bore and 63mm stroke deliver an extra 34cc, with peak power claims of 22 horsepower and 16.5 lb-ft torque (the 250 predecessor claimed 22 hp with 14.9 lb-ft torque).
