2012 Brammo Empulse Specs Released

Share this Article

Brammo revealed official specifications for the production version of its long-anticipated Empulse.

The Oregon-based company will produce two versions, the Brammo Empulse and the Brammo Empulse R. Brammo has released new specifications for the R version though it’s not clear what differentiates the two models. The Empulse R will likely be a faired version similar to the Empulse RR TTXGP racebike. More specific differences will come when both versions of the Brammo Empulse are revealed May 8.

We do know that both models will use water-cooled permanent magnet AC motors with six-speed transmissions. According to Brammo, the Empulse R can reach a top speed of over 100 mph. Brammo claims a range of 121 miles in the city (stop-and-go traffic with an average speed of 19 mph), 56 miles on the highway (at a sustained speed of 70 mph), and a combined range of 77 miles in half-city, half-highway riding.

The Empulse R operates in two riding modes, selectable through a handlebar-mounted switch. “Normal” mode optimizes range by limiting acceleration through reducing the maximum current level. “Sport” mode offers maximum performance by not capping acceleration or speed.

Brammo’s BPM 15/90 lithium-ion battery has a 10.2 kWh capacity which can be charged with Level I and Level II J1772 charge stations. Brammo says the battery can be fully charged with the 120V Level I in 8 hours while the 240V Level II can fully charge the battery in 3.5 hours. Brammo also claims a range of 5 miles for every ten minutes of charging at Level II. The battery also gets a charge through regenerative braking.

The Brammo Empulse R is equipped with a 43mm Marzocchi fork and Sachs rear shock, both of which are fully-adjustable. The front wheel is equipped with dual 310mm brake discs with radial-mount four-piston Brembo calipers while a single two-piston Brembo caliper grips the rear disc.

“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 8th people are going to be blown away by the integrity of the design and the focused presence this motorcycle commands,” says Craig Bramscher, Founder and CEO of Brammo. “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.”
