This has to be the lamest super hero photo I have ever seen, but the bike is cool. This is Lynda Carter playing Wonder Woman on the TV series, Wonder Woman, which aired March 10, 1979. The episode is
A Date with Doomsday, and the motorcycle is a 1978 or 1979 Yamaha IT175. The 1978 and 1979 Yamaha IT175 look identical, so its hard to tell the difference, but I am going to guess they were able to get a new 1979 model for this episode. The Yamaha IT175 was manufactured from 1977 to 1983, and it was a single cylinder two stroke motorcycle designed for competition use in enduro racing. Enduro racing was also referred to as International Trials, which is what IT stands for in IT175. This was a fun motorcycle to ride and it was quick. It wasn't as quick as a same size motocross bike, but it was quicker than most other two stroke motorcycle's of similar displacement. The bike came with a low/high beam head light and tail light, so it could be ridden at night. Behind the front number plate is a round speedometer/odometer, so you could keep track of your pace. The pouch behind the seat was used to hold a small tool kit and whatever else you could fit like a spare spark plug.
