This 2003 Grinnall Scorpion III is a British three-wheeled vehicle finished in yellow and powered by a mid-mounted 1,171cc inline-four mated to a five-speed manual transmission sourced from a BMW K-Series motorcycle. Other BMW motorcycle equipment includes an enclosed driveshaft, a single-sided swingarm, and a gauge cluster, while additional features consist of grey seats, four-point harnesses, a Momo steering wheel, chrome roll hoops, rearview mirrors, street lighting, and a tinted windshield. The vehicle was imported to the US as a factory-built roller and registered in California by the original owner, from whom the seller acquired it in 2017. Service at 3k miles is said to have included fitting a flow-through coolant temperature sensor and new radiator hoses, and changing the oil and coolant. This Scorpion III is offered with a clean Illinois title in the seller’s name listing it as a motorcycle.
