Vespa GTS 300, 2009
TECHNOLOGY
The increased engine performance has been designed to provide maximum performance in pick-up and acceleration - essential qualities for city commuting.
The displacement of the 4-valve single cylinder Quasar, with electronic injection and liquid-cooled, is now 278 cc thanks to the increase in both the bore (now 75 mm), and the stroke (63 mm).
The new GTS 300 Super is different from the GTS 250 because the new engine has a higher level of torque (22.3 Nm as opposed to 20.1) along with fewer revolutions per minute (5,000 rpm as opposed to 6,500 on the 250). On the road, these numbers translate into flexibility and pick-up from low speeds that are unequalled in this displacement category. So the Vespa GTS 300 Super is the perfect vehicle for the city, where it can show off the very best of what it has to offer.
Vespa is the only scooter in the world with a steel frame - an exclusive design feature that has set Vespa apart from other two wheelers ever since the first model was brought out in 1946.
Put simply, the Vespa does not have a welded plastic-covered tube frame. Instead it is the "body", made entirely of steel, which supports the engine and all the mechanical parts.
It's a design philosophy that gives Vespa superior rigidity (up to 250% more than a scooter with a tube frame), providing incredible precision control and sturdiness that is now legendary.
Inside the Vespa GTS 300 Super frame, underneath the seat, is the fuel tank. Although it can hold a good 9 litres of petrol, giving all the advantages of fuel distance, this does not restrict the under-seat storage space or easy access to the engine once the helmet carrier, which can hold two demi-jet helmets, has been lifted off (no tools required).
To the rigidity of the frame, the Vespa GTS 300 Super adds a chassis featuring 12" wheels with a size 120/70 tyre on the front and a size 130/70 on the rear.
The front suspension has the classic link arm, a traditional feature in Vespa history with excellent dynamic functional characteristics: this system separates the support and shock-absorbing functions, resulting in neutral braking and an anti-lunge effect. The spring in racing red is a distinctive feature of the Vespa GTS 300 Super.
At the rear, two spring pre-load-adjustable hydraulic shock absorbers are fixed to the transmission crankcase and exhaust support.
