The Chaly, like the Dax, differs from this series of mini motorcycles by its one-piece enveloping frame, both bodywork and support for the various mechanical components.

The Chaly differs from its elder Dax by a V-shaped frame, guaranteeing better comfort for women and which gives it a more utilitarian use, particularly on the Asian market where it can also be equipped with a fixed basket.

[5] The Chaly and the Dax have in common a horizontal single-cylinder 4-stroke engine with two valves and an overhead camshaft, small ten-inch wheels, two drum brakes (the front operated by a handlebar handle, the rear by a pedal on the right foot, except for the first CF50I model reserved for the Japanese market), a compact and robust architecture as well as a semi-automatic three-speed gearbox.

This small engine block, fitted with a 6 V electrical system, is appreciated more for its discretion, low fuel consumption, flexibility and strength than for its power.

[6] Well suited to driving in an urban environment, it is highly sought after for its compactness which makes it easy to board a car, a motorhome or a boat.
