Their creation is labelled as the UMC-063 Zero XP, which was taken from Zero SR/F based model of nearly £18K producing 110bhp and 140ftlb TQ out of its ZF75-10 electric motor powered by ZF14.4 Lithium-ion Battery.

Bike builders Hugo Eccles was given early access to the production bike prior to its release so that he could design and create this one of a kind electric power house.

It was recently shown at the Goodwood Festival of Speed with many changes made from the stock bike which include bodywork and frame, wiring, switchgear…in fact it looks totally different…and that’s how a custom bike should be.


Other changes are clip-ons bars with an internal electronic throttle, braided lines and Pirelli Diablo Superbike slicks tyres. Stark bodywork shows off the electric motor in all of its glory.

“This isn’t about novelty for novelty’s sake, or some nostalgic idea of the future,” Eccles said in a statement. “The goal is to celebrate this unique riding experience through an entirely new function-led aesthetic. If the Zero XP looks futuristic, it’s because electric motorcycles like the SR/F are the future.

“From the outset I knew that I didn’t want to hide the powertrain behind a fairing. I wanted to unapologetically celebrate the character of this motorcycle.”

Zero’s Brian Wismann, said: “We appreciate how [Hugo] works with a select group of brands on a few carefully-chosen projects. We’d been looking for the right opportunity to work together for a while and felt the SR/F was the perfect fit.

“Hugo is one of the most interesting designer-builders out there and it shows with the Zero XP. You can really see his industrial design perspective in every detail. He’s created something truly exceptional.”
