Lightning Bolt is an American-built streamliner motorcycle that held the motorcycle land-speed record from 1978, when Don Vesco rode it to 318.598 miles per hour (512.734 km/h),[2][3] until 1990.[4][5] It was also the fastest vehicle participating in the 1978 Bonneville Speed Week with a one-way 333.117-mile-per-hour (536.100 km/h) run.[6] It was powered by twin turbocharged inline-4 engines sourced from a Kawasaki Kz1000,[1] with a combined displacement of 2,032 cc.[7] The near-stock engines were linked at both ends of their cranks by two Gilmer belts and utilized the rear engine's gearbox.[8]
Lightning Bolt was apparently succeeded by another streamliner based on two turbocharged six-cylinder Kawasaki motors (probably from the early-1980s Kawasaki Z1300) that did not set records.[9] Vesco turned his attention to automobile land speed racing in the 1990s with a six-wheel car called "Skytracker" that Vesco described as a "cross between a car and a motorcycle",[10] then his final vehicle, the land speed record-setting #111 Turbinator.
