Kiyonaga-san opened Kiyo’s Garage in Los Angeles in 2013. Around the same time, he built ‘Cherry Blossom,’ a stretched land speed racer with a turbocharged Honda CB750 motor in a scratch-built frame. A few years later ‘Gekko’ followed?another 1970s top fuel-style bike, except this one had two CB motors.
The Galaxy continues Kiyo’s obsession with this theme. ?The concept common to all three is a land speed racer with the beauty of a show bike, which can actually run,? he explains.

Even though Kiyo already had a twin-engined bike under his belt, the step up to three was daunting. ?I was skeptical about whether it was possible or not,? he confesses. ?However, when I started making it, that anxiety disappeared, and I was able to complete a mechanism that was surprisingly efficient, simple, and fully functional.? The Galaxy’s four-cylinder power plants are all 1978 Honda CB750 units with F2 large port heads. Each motor has been bored out to 836 cc, and fully rebuilt with lightened and balanced crankshafts, heavy-duty connecting rods, performance cams and oversized stainless steel valves. Extra care was taken to make sure each motor’s internals conformed to the exact same spec.
