Product description
Stefano BENELLI has been passionate about all possible petrol-driven vehicles, either two or four stroke, since the 1980’s. His love of the two-stroke is strong and especially for the Vespa. This is where he could gather his first experience in motor tuning and many of his developments have seen successful use in scooter sprint racing. He found that the original Vespa gearbox was unable to cope with the extra power. Back in the days when the only aftermarket gearbox component available here in Germany was a shorter 4th gear for the smallframe engine, the BENELLI range of gearbox parts were already being included in scooters racing in the Italian national racing series. In more recent times gearbox parts from a number of manufacturers have become available. Outside of his home country of Italy, parts produced by BENELLI were very hard to obtain and only a small exclusive circle of racers and tuners were even aware of their excellent reputation and existence. During product comparisons conducted in Germany his gear cogs were rated better than those from other component manufacturers. Nowadays the BENELLI enterprise has become a small-scale producer of high-end gearbox components using the finest materials suited for a wide spectrum of potential employment. They have proven successful for use in off-road, circuit and sprint racing machines. Differentiation of 4-speed Vespa Smallframe gear selectors. For the 4-speed engines of the Vespa Smallframe models, there are two different gear selectors that fit different gearboxes or their gearwheels. There are two characteristics that distinguish the two types of gear selectors. 1. the shape of the transition to the upper end of the selecor. The later “PK type” has a radius there, i.e. round. The earlier “V50/PV type” is angular at this point. 2. the overall height of the gear selector. The “PK type” is 50.2mm high, the “V50/PV type” is 51mm high. Today there is a whole range of manufacturers who produce gear selectors for tuning and racing purposes. Unfortunately, some suppliers no longer adhere to the classic distinguishing features. DRT, for example, no longer produces the round gear selector and CRIMAZ, for example, produces the 50.2mm gear selector in 48.8mm. Therefore, we have decided to indicate either “type round/50.2mm” or “type square/51mm” for each 4-speed smallframe gear selectors.
