The Hot Rod Custom Show in Yokohama is one of the best custom shows in the world. Insane hot-rod cars and bikes of all kinds are brought to the port city outside of Tokyo for this one-day event, showcasing some of the most unique talents in both the car and motorcycle worlds. While there are hundreds of thousands of dollars poured into single machines that line the rows, there is something about minibikes that captures our imagination and gets us so excited. They’re small, approachable, affordable, and a great way to showcase creative talent without a lot of money.

This year, organized around the Mooneyes event, there were several flat-track races taking place, namely the “Have Fun!” horizontal-engine races, showcasing smaller-engined bikes, many of which are shown here in this gallery.

The bikes ranged from full frame-up customs like the ones constructed by Cheetah, to modified originals like the raked and extended orange Honda trailbike pictured. Every one of them a rad little representation of their owner’s creativity. I don’t know about you, but I got on Craigslist and started looking up minis as soon as I got home.
