With a powerful 250cc, four-stroke, four-valve engine, the GTS has the largest displacement in the Vespa range. Advanced technology, including a liquid-cooled engine and electronic injection system with three-way catalytic converter, allows for reduced emissions and fuel consumption as well as progressive acceleration and responsive handling. Redesigned machinery, such as the exhaust, cylinder and piston, provide a smoother and quieter ride that suits the stylishly racy GTS without affecting performance.

Like every other Vespa, the GTS has the trademark single shell steel structure which provides rigidity for optimal comfort and strength to control road vibration. The frame is supported with excellent parts including 12" wheels, dual-disc braking system, a front suspension with hydraulic shock absorber, and an adjustable rear suspension that provides ideal support and riding comfort for driver and passenger alike.
