German motorcycle manufacturer BMW Motorrad, in association with the Technical University of Munich, unveiled the all-electric, zero emission eRR study motorcycle.

The study model's design and chassis technology is based on the S 1000 RR supersport motorcycle. The in-line four cylinder, 999cc engine developing 196bhp and 133Nm of torque in S 1000 RR made way to an all electric unit in eRR. The detailed powertrain specification has not released yet.

However, BMW has mentioned C evolution scooter as an example of zero emission, riding fun and practical vehicle from the press note of the eRR. This raises the possibility of a liquid-cooled electric motor receiving power from an air-cooled lithium-ion battery pack.

Being an electric vehicle, the eRR is devoid of exhaust. Interestingly, the twin headlamps have also been given a miss. Being a study model, the production version might take longer time.

"We asked ourselves: What happens when combining a sport motorcycle and an electric drive? The experimental vehicle eRR brings the topic zero emission and electric drive on a new, more fascinating level," said Stephan Schaller, Head of BMW Motorrad.
