12th November 2024, Northampton, UK – The world of electric motorcycles has just witnessed a significant leap forward, thanks to an exciting collaboration between White Motorcycle Concepts (WMC) and Zero Motorcycles. Together, the two companies have unveiled the WMCSRS Intelligent Aero Prototype, the world’s first electric sports motorcycle to incorporate WMC’s patented intelligent aerodynamic duct, making its global debut at Motorcycle Live in Birmingham, UK, from 16-24th November 2024.
The WMCSRS concept, which re-engineers the existing Zero SR/S, represents a fusion of cutting-edge aerodynamic technology and electric vehicle (EV) performance, demonstrating the potential for groundbreaking improvements in the field. Through this innovative project, WMC has proven that aerodynamics can play a pivotal role in enhancing EV motorcycle range and performance—offering a 10% reduction in aerodynamic drag at highway speeds.
The Power of the Duct
The secret behind the WMCSRS is a bespoke bifurcated aerodynamic duct that runs directly through the centre of the motorcycle. This ingenious design channels air from behind the front wheel and directs it smoothly through the bike’s frame, exiting above the rear wheel. This radical alteration of airflow is crucial in improving the bike’s overall aerodynamic efficiency.
To maximise the effectiveness of the duct, WMC and Zero Motorcycles have also developed new aerodynamic components, including a custom-designed front fender and fork shroud package. These modifications ensure that airflow through the duct remains optimal, thereby further enhancing the bike’s aerodynamic performance. The result is a more efficient, more stable ride at high speeds, with lower energy consumption.
A Collaborative Innovation
The collaboration between WMC and Zero Motorcycles began in November 2023 at the EICMA Motorcycle Show in Italy. There, both companies shared a common vision of advancing innovation in electric motorcycles and improving range performance to meet growing customer expectations. Zero’s existing SR/S architecture—already known for its superior handling and performance—was identified as an ideal platform for integrating WMC’s aerodynamic duct.
Following an accelerated development programme that drew from WMC’s experience in Formula 1 and world sports car programmes, the team quickly realised the potential of combining computer fluid dynamics simulation, aero rakes, and rigorous prototyping to develop the first working prototype of the WMCSRS concept.
Robert White, founder and CEO of WMC, commented: “The whole industry is currently facing a huge technical and commercial challenge to produce an electric motorcycle with performance close to its petrol equivalent. This problem space will not be solved by battery technology alone—it requires a blend of innovations to bridge the gap now and provide efficiency benefits in the future.”
He continued: “When I first saw the Zero SR/S frame and battery architecture, I immediately recognized the opportunity to retrofit a duct. I’m proud of what we’ve achieved, though the duct would offer even greater performance if integrated from the start of a motorcycle’s design.”
The Efficiency Gain: How the Duct Works
The core benefit of the intelligent aerodynamic duct is its ability to reduce drag by 10%, which translates directly to increased efficiency. By improving aerodynamic performance, the duct allows the WMCSRS to maintain higher speeds and extend its range at highway speeds. This technology makes it possible to achieve more with less, reducing the need for larger, heavier batteries. In doing so, it also helps to lower overall weight, charge times, and battery costs, all while keeping the motorcycle’s performance intact.
Zero Motorcycles CTO, Abe Askenazi, added, “From our initial meeting at EICMA, we have been interested to understand the potential impact of WMC’s aerodynamic duct. 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. This proof of concept has given us valuable insights into the potential benefits of integrating an aerodynamic duct into electric motorcycles, and we will continue to explore complementary technological advancements.”
A Sustainable Vision for the Future
WMC’s innovative duct technology is not just a short-term fix. As battery energy density increases in the coming years, the potential for even larger ducts becomes a reality. This creates a virtuous cycle, where a larger duct allows for smaller batteries, leading to less weight, and subsequently enabling larger ducts to be integrated into the design. The end result is a continuous improvement in range and efficiency, with all benefits consistently growing over time.
The WMCSRS concept also aligns with the broader automotive industry’s pursuit of sustainability. Just as electric and hybrid cars have become 30% more efficient in the past five years, the motorcycle industry is now in a position to embrace complementary solutions—such as aerodynamics—to extend range and enhance performance, while reducing dependency on larger batteries.
A Look Towards the Future
As the motorcycle world converges on the Motorcycle Live event in November, the WMCSRS stands as a beacon of what is possible when two visionary companies unite to tackle one of the most significant challenges in the electric motorcycle market. This collaboration sets the stage for an exciting future, where technological advancements in aerodynamics, battery performance, and design come together to create the ultimate electric sports bike.
The WMCSRS will be on display at Motorcycle Live in Birmingham at the Zero Motorcycles Stand 4A15, offering attendees a first look at the world’s most innovative electric motorcycle prototype. With this debut, WMC and Zero Motorcycles have set a new benchmark for the electric motorcycle industry—one that will undoubtedly shape the future of performance, efficiency, and sustainability in electric vehicles.
