Street Hawk is an American superhero television series that aired for 13 episodes on ABC in 1985. The motorcycle in the pilot episode was based on a 1983 Honda XL500 trailbike. Motorcyclist Magazine staffers Jeff Karr and Dexter Ford built the motorcycles for the pilot by combining parts from an electric start Honda 500 Ascot with the chassis of a dual-sport XL500 on/off road bike. The motorcycles used in the series were based on 1984 Honda XR500s, using the electric-start motor of the street-based Ascot, creating the first-known electric-start Honda dual-sport motorcycles. The stunt coordinator insisted on using the turbocharged Honda CX500 street bike for performance-related sequences, but the motorcycles actually used for the stunt shots were based on Honda CR250 racing dirt bikes. The bodywork of the pilot motorcycle was designed by Andrew Probert and the series motorcycles were redesigned by Ron Cobb. During filming, the fiberglass bike parts constantly flew off the bike during the course of stunt work. The film stunt second unit crew always had six bikes standing by to replace the hero bike's jump or maneuver. When first unit was on stage at Universal Studios, the second stunt crew were on location filming with a stunt biker performing with the bike. The stunt bikes were always in Universal Studios' effects shop being repaired or replaced with parts.
