VESPA S 50 4 Valves

Vespa maintains the lead that has lasted over sixty years.

The new Vespa S 50 4 Valves brings you all the pleasure and lightness of a 50 cc Vespa.

The high-tech little 4 Valves combines the sparkling performance of a two-stroke 50 with the fuel economy and low emissions of a 4 stroke.

The engine: at last a four stroke as brilliant as a two stroke.

The new four valve, four stroke Vespa 50 rediscovers a legendary engine size that has played a major role in the history of Vespa. Thanks to a 4 valve cylinder head, this brand new little powerplant has nothing to fear from its two-stroke competitors. (At 4.35 bhp it is the most powerful 50 cc four stroke on the market.) Yet its consumption and emission figures remain those of a typical four stroke.

The new engine is a little jewel of technology: use of a 4 valve head has led to an increase in power of over 23% compared to the previous 2 valve configuration (4.35 bhp against 3.53 bhp). Power output is therefore the same as that of a high performance two-stroke.

The valve clearance adjustment mechanism has been made lighter to achieve less inertia and a more efficient rocker/valve action. The result is higher engine speeds and more power. Improved through-flow, also the result of the four valve head, means optimised combustion, reduced fuel consumption and lower than ever emissions.

The new engine delivers fuel consumption figures (ECE 47 cycle) identical to those of the extremely parsimonious 2 valve four stroke, and significantly better than those of the two stroke version (36% less).

The new engine has been designed, developed and industrialised at Piaggio’s headquarters in Pontedera, one of the world’s most important centres for engine R&D. Piaggio is determined to offer today’s ever more sophisticated scooter riders performance, reliability and safety, and respect for the environment too.

Vespa S

The Vespa S is the first model to be equipped with the new 4 valve engine.

The brilliant new four valve 50 cc engine makes the most of the light weight of the Vespa S to offer young riders the perfect solution to their needs for personal mobility and freedom, exactly as Vespa has done for generations of teenagers, boys and girls alike. With the Vespa S 4 Valves, however, fuel consumption and ecology are better than ever.

Style and technology. Vespa is unique in the world.

The Vespa S relives the fascination of the original sporty “Vespino”.

The unique styling of the Vespa S is a clever blend of past echoes and reflections, and interprets the young and sporty soul of Vespa in the present day. The rigorous, minimalist design of the Vespa S embodies a heritage that dates back to the legendary models of the 1970s, like the 50 Special and Vespa Primavera.

The Vespa S is also available in 50 2T, 125 and 150 cc versions, all of which share the same sporting, dynamic and fresh character. Its lines are clean and essential. With its minimalist but decisive styling, simple yet elegant design, the Vespa S features the same dynamism and freshness that made the Vespa the favourite scooter of young people in the roaring seventies.

As has always been the case in the long history of Vespa scooters, the steel body acts as the frame.

The front suspension features a double acting hydraulic shock absorber with an aeronautical style lateral arm. At the rear the Vespa S is equipped with a suspension system based on a double acting hydraulic monoshock. An 11” front wheel guarantees excellent stability and gives the rider a feeling of confidence and safety. The tyres are both tubeless, 110/70 at the front and 120/70 on the 10” rear wheel. The braking system is a classic disc and drum combination.
