This 1973 Yamaha TX650 isn’t a motorcycle. While it might look like one, in reality it’s a fully functioning time machine. That’s because owner Keith Allen is connected to this particular motorcycle in ways most of us could only imagine.

“In the early summer of 1973 I was 16 years old,” Keith explains. “I’d been riding and racing dirt bikes, and my dad and I went to the Honda, Harley-Davidson and Yamaha shop Zanotti Motors in Butler, Pennsylvania, because he wanted to get a 2-stroke Yamaha RD350 street bike.

“When we got into the dealership there were five TX650s lined up in the window, and I steered him towards the larger 4-stroke motorcycles. He wrote a check for this one and tossed me the keys, telling me to ride it home.”

Keith had only just received his driver’s license, and the road home was a major four-lane highway. Back in 1973, the Yamaha 650 was considered a big motorcycle, and Keith was slightly nervous. “Once I got on it I wasn’t stopping, and the nervousness disappeared after a mile,” he says, chuckling at the memory.
