2012 Brammo Empulse R

Brammo has finally started showing the press the production version of their Empulse R electric motorcycle. It’s widely being regarded as the first electric that is on par with a gasoline powered bike in terms of both performance and experience. They key component responsible for the Empulse’s merits is its 6-speed transmission. Electric vehicles generally use a single gear ratio because they take advantage of the fact that electric motors pretty much make maximum torque at all rpm’s. This means that the motors don’t have to be spun up to high rpm to make power but the instant torque can very easily grenade a transmission designed for a gasoline engine that does. Brammo has bought exclusive rights to a 6-speed transmission designed specifically for use on electric motorcycles. The extra gear ratios allows the motor to stay at its most efficient operating point but more importantly it makes the electric motorcycle experience as engaging as what motorcycle riders are used to.
