London and Californian based custom motorcycle builders, Untitled Motorcycles, have created a one-off electric naked, based on the Zero SR/F.

Known as the Zero XP, the bike began life as the firm’s £17,990 (for the standard model) SR/F, which arrived in dealers in May 2019 and produces 110bhp and 140ftlb of torque from its ZF75-10 motor and ZF14.4 lithium-ion battery.

The bike was built by Untitled’s Hugo Eccles, who has previously worked on large-scale projects with the likes of Ford. He was given exclusive access to the pre-production machine during the final stages of its development, in order to create the drag bike-inspired XP.

Debuted on Thursday, 4 July at the Goodwood Festival of Speed, just the seat and footpegs are retained in the same position, with a large portion of the switchgear and all of bodywork changed to create a futuristic naked streetfighter.

Offering a stripped-back take on Zero’s premium roadster, changes to the bike include custom clip-ons with an internally-housed electronic throttle, braided lines and Pirelli Diablo Superbike slicks. Minimalist bodywork is also used deliberately in order to show off the electric motor.

The bike makes use of many standard ancillary components though, including dual 320mm NG floating front discs with dual J.Juan 4-piston radial calipers.

“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.”

His comments were added to by Zero’s Brian Wismann, who 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.”
