The right hand controls the throttle, the left hand manages the clutch and gears, and the right foot operates the brake—this was the control method for vintage Vespa models, as shown in the video below:

When Vespa first emerged in the late 1940s, designers integrated the gear shifter directly into the left handlebar grip. Riders shifted gears by twisting the grip while engaging the clutch, keeping both feet flat on the floorboards instead of reaching for a foot lever. This design made the scooter more accessible to new riders and ideal for daily urban commuting.

The system utilized a mechanical linkage running from the handlebar down to the gearbox, converting the twisting motion into precise gear changes. Gear positions were marked on the handlebar unit, allowing riders to easily see which gear the scooter was in. Despite its unconventional appearance, this design was very reliable and became one of Vespa's most recognizable features.

This handlebar gear shifter layout remained a core part of Vespa's identity for decades, even as engines and frames evolved. It emphasized comfort, simplicity, and ease of use, setting Vespa apart from motorcycles that used foot-operated shifters. Today, the twist-grip gearbox is a distinctive detail that instantly identifies vintage Vespas with manual transmissions from their early days.

The same gear-shifting method was used by vintage Lambretta models, as shown in the video below:
