The SP400 was a single-cylinder, overhead-cam four-stroke dual-purpose bike that arrived in early 1980 as a trail-style machine. It rides on a 21-inch front and 18-inch rear wire-spoked wheel with drum brakes at both ends and a simple single-downtube frame. Colours offered were red, blue or silver, with a black engine and high-level exhaust.
