According to 'Maxiscoot', when the Stalker was first launched; "The intention of the Stalker couldn't be more clear, its typical, aggressive-looking 50cc with its raised chassis leaves no room for doubt - it's meant, designed and built for fun. its chassis is well designed and makes handling it really enjoyable right out of the box. But its real focus is on the air-cooled Piaggio engine with really great performance and will develop into a real beast when properly upgraded and tuned. The Gilera Stalker equally caters to the everyday rider who wants a street-legal, fun and fast machine, as well as those who are looking for a reliable starting point for track racing and competition"You can see why Barrie loved this little bike and frequent references were made to his long-established nickname and his progress through a crowded paddock.Single cylinder, two-stroke, 49.3cc, separate lubrication with automatic mixer, belt drive, automatic gearbox, dry clutch, front disc brake - 7.5", drum - 4.3"on rear.
