Later US models also had the traditional Lambretta tail light removed, and a special "tractor style" tail light added in order to conform to US regulations. The ignition key was moved from the back of the headset on the Inocenti models to a position at the rear of the seat on the Servetas, which often caused the keys to scratch the top of the sidepanel in this area.
Floor runners were eliminated, and black rubber floor mats were used instead. Both models came with dual saddle seats and rear spare tire racks as standard in the US. The Jet did not come with the disc brake system fitted to Italian cc machines except on some very early Jet models.
It does not appear that any of these disc brake Jet 's were imported to the US. The Jet did however retain the dampeners used on the SX. On later models, the dampeners were modified and enlarged. The motors are essentially the same on the Italian and Spanish made bikes, but there are some differences. Some parts were sourced in Spain for the Servetas, most noticeably, the flywheel magneto system which was made by Motoplat.
One other thing to note, the Servetas had an air filter which was located inside the glovebox rather than in a separate airbox. This was a vast improvement in strength over the old Innocenti design and these hubs would fetch a premium as they were far safer for highly tuned Lambretta engines, predominantly for scooter racing.
The rear shock absorber would also be beefed up with much wider frame and engine mountings as well as an up rated spring. Again this would give a much improved ride certainly two up and was an improved safety aspect. When it comes to the wiring and electrics of the Jet one must wonder what the hell they were thinking when they designed the layout. Not only was the wiring system immensely complicated it was also cluttered and untidy.
Even a degree in astrophysics would not be enough to work out the mass of tangled wires that made wiring the space shuttle look a doddle. The problems stemmed from the amount of warning lights, switches and indicator system that worked their way around the frame. Initially the system was fed by a Motoplat 6V ignition system which in all honesty could have done with being 12V for the amount of systems it had to run.
From here it fed in to a regulator which is where the complicated journey began. Feeding to a rather large capacitor for the indicators which was crudely tied to the frame with a rather odd black rubber band this signalled the troubles that lay ahead. There was a mass of wiring which fed off to each indicator that then backed up to the head set where the switch that controlled them was placed. This was combined with a wire from the back of the engine up to the head set for the neutral indicator light.
The light was tightly crammed above the speedo with another for the indicators and one for a newly incorporated feature, a headlamp flash. This is where the real problem lay as there was now a mass of wires in to the head set and to compound matters further quite often not colour coded. With the extra switches this meant that the gear change on the handle bars would have to house a switch as well, complicating the wiring even further.
With what was seen as the crowning glory of the ludicrous wiring design the switch was now placed at the rear of the frame on the right hand side just to the edge of the rear frame badge. This allowed for two things — another set of wire feeds along the frame and the unwelcome opportunity to cut your leg open as you got on the machine since the ignition key jutted out from the side.
Not forgetting those that wished to fit a Snetterton seat would now need to cut out a small recess at the back to fit around where the key went. There was no doubt that the wiring on the Jet was a complete enigma not only to owners but probably to those that fitted it in the factory.
While it worked all was fine but once there was a problem the best thing to do was pray. Serveta did supply a small wiring diagram that came with the instruction manual but it would be easier to read Egyptian hieroglyphics than try to decipher what was actually printed in the manual. The Serveta Jet overall was a good well-built machine. Though it had its faults, certainly with its wiring, it proved on the whole to be reliable. Though there were some improvements not all were designed that well, which if anything was its only downfall.
There are many original examples still being used today, which demonstrates how its exemplary build quality has stood the test of time. With the ridicule attached to owning a Jet long gone it can now finally take its rightful place as an iconic machine among Lambretta owners. Quite early on the Special and SX legshield badges were replaced with Jet badging. With Innocenti having ceased to produce scooters, the firm parts began to be replaced with uniquely made Spanish items. Also the air filter was rehoused in the toolbox, with a vented door allowing air intake.
Some of the more notable were indicators on chrome stalks, GP inspired panel stripes, sealed unit 6v headlamp and upgraded electrics and switches. Also in the name Serveta was replaced by Lambretta SAL, where scooters were made alongside washing machines. The Spanish cc machines had their frames stamped SX starting Enjoy more Scootering reading in the monthly magazine. Click here to subscribe. Skip to content Facebook Twitter.

The engine sounds very sweet. Low mileage That said.
