It’s one thing to build an avant-garde custom bike. It’s entirely another to take said bike to the heat of El Mirage, and run it in the world’s fastest automotive speed trials. But that’s what Chabott Engineering founder Shinya Kimura (left, above) just did. He clocked 87mph (141kph) on his 1946 Knucklehead ‘Spike’, balloon tires and all. Reader Anthony Byrd was there, and sent us the pic to prove it.
