White Motorcycle Concepts (WMC) and Zero Motorcycles have collaborated to prototype the world’s first electric sports bike with WMC’s patented aerodynamic duct, reducing drag by 10%.
The companies first connected at the 2023 EICMA motorcycle show, where they shared a vision focused on advancing electric vehicle efficiency and performance. The design of Zero’s SR/S model made it an ideal candidate to integrate WMC’s aerodynamic technology.
The resulting WMCSRS concept features a bespoke bifurcated duct that channels air from behind the front wheel and exits above the rear wheel. To enhance airflow through the duct, WMC also designed a new aerodynamic front fender and fork shroud.
“The whole industry is currently facing a huge technical and commercial challenge to produce an electric motorcycle with performance close to its petrol equivalent,” said Robert White, Founder and CEO of White Motorcycle Concepts. “This problem requires a blend of innovations to bridge the gap, not just relying on battery technology alone.”
According to White, when he first saw the Zero SR/S architecture, he recognized the opportunity to retrofit WMC’s patented duct technology. The resulting proof-of-concept demonstrates the potential benefits of integrating aerodynamic enhancements into electric motorcycles.
“Aerodynamics is a hot topic, especially in MotoGP, where winglets and other devices improve lap times, though this efficiency benefit does not always translate to retail bikes,” White explained. “Our intelligent aero duct enhances aerodynamic efficiency, positively impacting power consumption, especially at high speeds.”
The WMCSRS features a vertically bifurcated duct that picks up air behind the front wheel and navigates the existing Zero SR/S structure, exiting just under the seat. Using F1-style aero rakes, the engineering team analyzed the airflow to optimize the duct’s performance.
“From our initial meeting at EICMA, we have been interested to understand the potential impact of WMC’s aerodynamic duct,” said Abe Askenazi, Zero Motorcycles CTO. “We are committed to innovation, and while battery development is advancing rapidly, we believe a combination of technologies is the key to developing the electric motorcycles of the future.”
The 10% increase in aerodynamic efficiency from the duct can be used to either extend the motorcycle’s range or reduce battery size and weight, cutting down on costs and charge times.
“This proof of concept has given us valuable insights into the potential benefits of integrating an aerodynamic duct into electric motorcycles,” Askenazi said. “We will continue to explore complementary technological advancements to deliver market-leading products for our customers.”
The collaboration between WMC and Zero demonstrates the potential for innovative partnerships to address the challenges facing the electric motorcycle industry.
