Right on schedule, Brammo has released the technical specifications of the Brammo Empulse & Brammo Empulse R electric street bikes. Featuring a 54hp water-cooled Permanent Magnet AC (PMAC) motor, the Empulse will come with a 10 kWh (9.3 kWh nominal) battery pack, and of course the Oregonian company’s six-speed gearbox. With fully-adjustable Marzoochi front forks, a fully-adjustable Sachs rear shock, Brembo brakes, & Marchesini wheels, Brammo has included some nice kit on the Empulse, though the company hasn’t tipped off to what the “R” designation will mean for consumers.
Our best guess is the Brammo Empulse will be a naked version that is very similar to the Empulse prototype we’ve seen from day one, with some cosmetic updates of course, while the Brammo Empulse R will be a fully-faired sport bike that strikes a similar line to the Brammo Empulse RR electric race bike.
Asphalt & Rubber‘s Bothan spies report that the gearbox works incredibly well, allowing the Empulse to operate just like a standard street bike with shifting and gearing control. There’s still some debate as to whether electrics need trasmissions, let alone close-ratio six-speed transmissions, but we’ll leave that debate for another day.
Still not releasing any images of the new Empulse and Empulse R, Brammo will be taking the wraps off its latest bike on May 8th at an event to be held in Los Angeles. The unveiling will also be live-streamed on the web as well. Click after the jump for the full technical specifications of the 2012 Brammo Empulse R.
