The clutch, gears and brakes found on most vintage geared Vespa and Lambretta scooters are operated by control cables leading from the steering assembly. Due to the frame design with engines mounted at the rear, this inevitably makes these items quite long. To ensure complete control they should be in perfect working order!
The length of control cables can vary once they have settled following initial use. These factors affect the mechanical play at the handlebar levers and foot pedal, which control the essential function of the clutch and brakes. To counter this adjuster screws are located at the component-end of these cables, allowing convenient adjustment of their operative length.
Over time these adjustment screws also wear, break, corrode or are damaged by contamination or mechanical wear and tear. Whatever the damage, they all require immediate replacement making it again possible to perfectly set up the control cables, this not only increases safety, but also restores full control over the operation and functions of the scooter.
