The Zero SR/F... like you’ve never seen before

Zero Motorcycles gave a new SR/F to custom bike builder Hugo Eccles at UMC, and the final result is stunning.


The Zero SR/F is one of the most legitimate-looking and performing electric motorcycles on the market today, but UMC custom shop has just revealed a sleeker, stealthier, and more attractive machine at Goodwood Festival of Speed 2019. 

This unique machine is called the UMC-063 ZERO XP | EXPERIMENTAL 2020 Zero SR/F.

According to UMC: ‘The ZERO XP is an experimental electric bike that explores the future of motorcycle design. The XP’s core is a machined aerospace-grade aluminum powertrain that contains the batteries, charger, and motor. The 14.4kW motor produces 140ftlb/190Nm of torque (almost 40% more than a Ducati Panigale), capable of accelerating the XP to 124mph/200kph with a single twist of the wrist’
