Vespa is the real stronghold of the whole Piaggio Group, and, in fact, the company keeps investing on its legendary scooter. This time it is the larger version, the GTS, that receives a shot of extra horsepower thanks to the substantial upgrading of the 278cc liquid-cooled four-stroke engine. Dubbed the 300 HPE, the unit now delivers a claimed 23.8 hp at 8,250 rpm with 19.2 pound-feet peak torque at 5,250 rpm. This makes the new GTS 300 HPE the most powerful Vespa ever. The whole powertrain has been duly upgraded also in its CVT transmission and related automatic centrifugal clutch. This should make the new GTS 300 HPE rather quick, and fun, through traffic. The Vespa GTS 300 HPE is offered in a number of variations, the richest being the SuperTech, featuring an exclusive 4.3-inch TFT full-color instrumentation display.
