To fill a Grande with fuel, the seat must be lifted and a bleeder valve must be opened to bleed air from the tubular frame while fueling. Two large steel tubes were used for the frame with a lower crossover pipe, connecting both tubes. While it's predecessor, the CB1 had a Gilera specific motor that came in 4 and 5 speed variations, early motors producing roughly 7hp.ĭue to the Grande's tubular style frame with integral fuel tank, the fuel tank was a unique design which resluted in slightly less fuel capacity then other Vespa. There was also a European version of the Grande, called the CBA that game in several styles all with the standard motor used on other models. The Grande Deluxe was a later model and came with an oil injection system these are very rare. One housed the battery and flasher for the turn signals, and other was for a tool kit and storage. The Grande was also available as the "Grande Super Deluxe" which came with turn signals and two side compartments. All Grande seats lifted up which is where a tool kit that was found inside a plastic tote, as well as the oil cup. All Grande came with a spring loaded chrome front "crash bar", or "foot rest", not found on other Vespa. Other parts for each version had MPH identifications in the respective part numbers. Grande also came in 20, 25, and 30 MPH versions, easily determined by the black and white sticker found on the right side of the sub frame with the side cover off stating 20, 25, or 30. All models had an option for front and large rear luggage racks in chrome or black paint. Base models also had one engine run/stop switch mounted to the handle bars, in comparison to the Deluxe models having a switch on the handle bars and a separate removable "igintion key" also mounted in the headlamp assembly. The base models speedometer was mounted externally and to the handle bars, whereas the deluxe speedometer was mounted inside the headlamp assembly. It came with a 2 1/2"x17" front tire and a 2 3/4"x16" rear tire both with different tread patterns (they were available with spoke wheels and mag wheels on later Grandes), automatic variable transmission, telescopic front fork suspension, and rear hydraulic shock absorbers.
