Overview Vespa 150 Sprint Veloce

In 1969, the Vespa Sprint 150 was presented in showrooms as the Sprint Veloce 150 following a comprehensive redesign. The frame remained unchanged, but was dominated by a handlebar head with a 130 mm round Headlight Unit. The Super series model was used as the speedometer. The large, angular Rear Light with a cover painted in the vehicle colour completed the new look. At the start of production, light grey plastic handles and side cover rubbers as well as a white speedometer dial were used. Over the course of the production period, these were replaced by black rubber versions. The Sprint Veloce practically functioned as the larger capacity sister model of the 125 GTR, although it was visually orientated towards this model.

Model history of the Vespa 150 Sprint Veloce

Compared to the Vespa 150 Sprint, the Sprint Veloce had a few differences. It had a large plastic rear light with a Cap painted in the vehicle colour, similar to that of the Rally models. Unlike the Sprint, it had no Decorative Trims on the sides of the cheeks and Mudguard. The handlebar head was fitted with a round Headlight Unit and a smaller shell speedometer, which was also reminiscent of the Rally and Primavera models. In terms of engine power, it surpassed the Sprint as it had three transfer ports instead of just two. Needle Bearings were introduced on the Lima side from 1976, as was the case with the PX models. From 1976, Bearing 613912 was no longer used on the alternator side of the Vespa, instead Bearing 4392C was used for the first time. This Engine, including the contact ignition, was the one that would later be found in the first models of the PX series.

The Engine of the Vespa 150 Sprint Veloce

The Sprint Veloce's Engine lived up to its name by offering significantly increased performance. This improvement was achieved by the introduction of a third overflow channel in the Crankcase and Cylinder, which optimised filling across the entire speed range. In addition, the increased compression ratio, the larger Dellorto 20/20 Carburettor and a more voluminous Exhaust contributed to the Sprint Veloce achieving balanced performance.

Miscellaneous Vespa 150 Sprint Veloce

  • Covers of the rear light of the Vespa Sprint Veloce were designed in the same colour as the bodywork.

  • The position of the frame number differed depending on the model: it was stamped on the edge of the frame under the left side cheek piece; on the German models it was located at the rear right (on the engine side) under the cheek piece.

  • In terms of Badges and Emblems, the Vespa had a two-line, relief-like "Vespa Sprint" lettering made of chrome-plated aluminium on the Legshield. The "Sprint Veloce" Badge made of the same material was positioned above the Rear Light at the rear. During the production period, the Badges changed both at the front and rear.

  • The Seat or Single Seat of the Vespa Sprint Veloce also had a characteristic design. The Floor Runners consisted of an arrangement of three strips, a rubber mat and another three strips.

  • Other special features included the Ignition Lock and the Indicator Switch of the German version. The Handlebar had a green Control Light, a shell-shaped speedometer with a white dial and a scale up to 120 km/h. A hexagonal Piaggio emblem was attached between the speedometer and the Control Light. At the beginning of production, light grey grips with embossed Emblem were used, later black grips, a black speedometer dial and black cheek rubbers.

  • The dimensions of the inner handlebar tubes of the German Sprint Veloce built in '77 were specific: 20.5 mm outside, 18.0 mm inside and a length of 318 mm. The clamp on the engine side was removable, but not lockable; the left clamp (battery side) was awkwardly bolted, as the fitting could only be accessed with a small spanner or a ratchet in the Battery Compartment.

  • The German Sprint Veloce had the Ignition Lock in the Indicator Switch, handlebar end indicators and a Battery. From engine number *294260 there was a large Cone, recognisable by the Limalager (Needle Bearing) and the small Wedi as on the PX. All models with a large Cone always had three transfer ports. The Sprint Veloce also had three transfer ports on Engines with a small crankshaft cone.
