CW Zon Debuts a Twin-Engine Royal Enfield Classic 650 at Mooneyes

The annual Yokohama Hot Rod Custom Show is poised to unleash a flurry of visual delights when it opens its doors to the public tomorrow. Colloquially known as Mooneyes, it’s not only Japan’s top show but also arguably one of the most prestigious in the world. So if you’re planning to unveil your latest build there, it had better be good.

Custom Works Zon founder, Yuichi Yoshizawa, and his right-hand man, Yoshikazu Ueda, are regular faces at Mooneyes with multiple trophies to their names. But this year’s CW Zon entry might be the shop’s wildest yet. It’s based on a Royal Enfield Classic 650—or, more accurately, two of them.

“Most custom motorcycles showcased at HRCS are powered by large-displacement engines,” says Yoshizawa-san, “and the engine’s visual impact is always a crucial element. The Classic 650 engine is beautiful, powerful, and full of character—but I wanted to elevate its presence even further. That’s how I arrived at the idea of using two engines.”

A twin-engine build is always an ambitious endeavor, but Yuichi had a specific vision for the build that would add an extra layer of complexity. Where most twin-engine bikes are typically stretched land-speed racers, he wanted something closer to the proportions of a chopper.
