2012 Brammo Electric Sportbikes

The electric-motorcycle manufacturer Brammo has released information about its upcoming Empulse and Empulse R electric sportbikes.

The Empulse and Empulse R, which will be unveiled May 8 in Los Angeles, will feature the “the world’s first drivetrain that has been designed and built for a production electric motorcycle.”

Some of the features of this drivetrain are a water-cooled permanent magnet AC motor, IET 6 speed gearbox and Brammo’s unique BPM 15/90 battery modules.

Brammo says: “This drivetrain package endows the Empulse and Empulse R with rapid off-the-line acceleration, sustained high speed and industry-leading range.”

And its quite rapid for an electric motorcycle; according to the Brammo’s spec sheet (listed below), the Empulse R has a top speed over the 100mph mark, and gets 121 miles to a charge. These claims give the Brammo Empulse R higher performance than the current electric sportbike leading the category, the Zero S ZF9 (114-mile range, 88mph top speed).

Craig Bramscher (Founder and CEO of Brammo) says: “The Empulse and Empulse R are a milestone for Brammo and the new electric benchmark for the motorcycling industry. I know when I reveal the bikes on May 8 people are going to be blown away by the integrity of the design and the focused presence this motorcycle commands.

“When we first revealed the Empulse prototype, our customers had some very clear feedback for us and that feedback has inspired much of what you will see in the production version.”

Both Empulse motorcycles featue the J1772 Level II on-board charging system, which will allow riders to charge the Brammo at perspective stations worldwide. Brammo says the Empulse and Empulse R can be totally recharged in just 3.5 hours and every 10 minutes of casual charging adds 5 miles of range.

Brammo says: “With a little planning, a day’s journey of 200 miles or more can now be achieved.”

The 2012 Brammo Empulse and Empulse R will be unveiled at the Boulevard 3 in Los Angeles on May 8.
