Reinforced Gear Selector from VMC for Vespa Smallframe Models. Developed for heavy-duty engines and precise shifting, even in the high-performance tuning sector.
The High-Performance Racing Cruise from VMC is made of high-quality chrome-molybdenum steel and designed for a certified surface hardness of 56 to 60 HRC using modern case hardening and vacuum hardening processes. The optimized inner profile reduces friction during shifting and ensures that gears can be changed cleanly and in a controlled manner, even in conjunction with particularly hard shift springs.
Designed for "long life" reliability, this Gear Selector can withstand even extreme loads on the road and race track. The scope of delivery includes a specially developed, reinforced shift spring and a pair of high-quality balls. According to VMC, the Gear Selector is suitable for Engines with more than 25 HP.
Not suitable for Vespa Primavera gearboxes built before 1976. The classic external dimension of 50.2 mm is not the only decisive distinguishing feature. Made in Italy.
Differences Between the 4-Speed Gear Selectors for Vespa Smallframe Models
For the 4-speed engines of the Vespa small-frame models, there are two different Gear Selectors that fit different transmissions or their Gear Cogs. The two types can generally be distinguished based on two characteristics.
- Shape of the transition to the upper end of the shift pawl: The later PK type has a rounded radius at this point, while the earlier V50/PV type is angular.
- Height of the Gear Selector: The PK type is 50.2 mm high, while the V50/PV type is 51 mm high.
Today, there are numerous manufacturers producing Gear Selectors for tuning and racing purposes. Unfortunately, some suppliers no longer adhere to these classic distinguishing features. DRT, for example, no longer manufactures the round Gear Selector as round, and CRIMAZ produces the 50.2-mm Gear Selector with a height of 48.8 mm.
Therefore, we have decided to specify either the round/50.2-mm or square/51-mm type for every 4-speed Gear Selector for Vespa Smallframe models.
