The engine (complete with three transfer ports) produced about 2 bhp more as compared to its installation in an ET3 – presumably this was accomplished by the increased compression ratio and slightly bigger carb size. The electronic ignition was not publicised this time around since this feature could already be found on some of the PK range, with the rest soon to follow. As with its predecessors, a large expansion box type silencer was fitted as standard – these being the only Vespas to feature such an item. An unfortunate consequence of one being fitted on this model was that there was no room for the side-mounted spare wheel found on other variants.
