This isn’t just any 42-year-old KX, though. It’s one of only three true factory works motorcycles hand built by Kawasaki in Japan for the U.S. factory race team of Jeff Ward, Tom Benolkin and Goat Breker. A historian at Kawasaki determined that only three bikes were shipped stateside.

It’s a five-speed SR250 from the collection of 500cc World Motocross champion Brad Lackey, a former factory Kawasaki rider himself. It’s been restored by factory Kawasaki mechanics and features titanium nuts and bolts throughout.

It was sold this week at the Mecum auction in California for $71,000.
