Gordon Mizuhara was an unusual teenager: He was never, ever interested in motorcycles. But he did want his own wheels, and carefully saved his money to get a set, at some point realizing he had enough for either, (a), an old beater of a car or, (b), a cherry 360T Honda motorcycle. He bought the Honda.

Naturally enough, after owning the little Honda for a few weeks, Gordon was suddenly an enthusiast. Then he started noticing the hotshots in his ocean-side neighborhood in San Francisco, many of them riding Yamaha 500 singles. “People would race them up and down the Great Highway. The Yamaha TT500 has stump-pulling torque, and some people could wheelie a TT500 for blocks. It was the Wheelie King,” Gordon says, and that got him hooked on the big Yamaha single.

Although the Yamaha TT500 was last imported into the U.S. in 1981, the lightweight, fun single still has tons of fans. “I don’t remember when I got the first one, but I’ve definitely been bit by the Yamaha 500 bug,” Gordon adds. “I have been collecting all three varieties — the TT offroader, the XT enduro bike and the SR road machine. I own eight now, and this bike is the earliest one in my collection.”

Rise of the machine: The 4-stroke motorcycle 
Although Yamaha got its start in the 1800s building instruments, it turned to motorcycles after World War II, when producing inexpensive transportation was one of the sure bets in the uncertain world of occupied Japan. Exports fueled the company’s growth — particularly to the U.S., where the company established an export arm in 1961 — and by the late 1960s Yamaha’s American market was probably bigger than its Japanese market, and possibly Yamaha’s single biggest source of income.

A lot of that success came from paying attention to the market. The Yamaha DT-1 scrambler introduced in 1968 was specifically built for the U.S. market, and was a huge success. “It was reliable,” explains John Reinhard, a former Yamaha USA employee and now owner of Ken Maely’s Hot Shoes (famous for its custom dirt track racing boots). “The levers would stay on the bars. Everything would work,” he says in obvious reference to the less-than-reliable fare coming out of the U.K.

I love your TT500 Yamaha, I owned one myself, yellow and chrome tank, I think it might have been a '78 model. I raced it in endure and motorcross in New Zealand against RM 370's and Honda 500's. I always seemed to make it to the first corner or the top of the hill before the rest of the pack. I couldn't hear the engine with the screaming 2-strokes were close so I made a megaphone exhaust with no baffels to drown them out, so I could tell which gear I was in in the heat of battle, worked a treat. I was the only 4-stoke racing at the time in the 2-stroke dominated 80's and early 90's. Loved every minute of it, especially when I won. I am looking for another one to restore and keep, if there is anyone willing to sell please get in contact at or tx. 0274432519 New Zealand.
