The 1967 MY BSA C15 S has, at its heart, an air-cooled, four-stroke, 249cc, single cylinder powerplant mated to a four-speed manual transmission and can produce a claimed 15 horsepower at 5000 rpm. It also comes with laced wheels with knobby tires mounted on them, a single seat, a telescopic front fork coupled to plunger shocks in the rear, drum brakes, a small headlight and mid-mounted foot controls.
