The power train consists of the patented IET™ system
In 2012 IET designed a powertrain for this bike, dramatically increasing its performance, speed and autonomy.
The 2014 Empulse is an evolution of the highly acclaimed, award winning Empulse. With its unique water cooled Hi-Perm-Mag motor developed by IET, six speed IET™ gearbox and integrated J1772 rapid charging, the Empulse is as the market leader in the category. A top speed of 110mph (177 km/h) and a 3 kW onboard charger means the Brammo Empulse retains its crown as the world’s fastest electric motorcycle in serial production both riding and charging. The 2014 Empulse embodies many new and improved components making it an EV technology tour de force.
With the ground-breaking IET integrated 6-speed transmission, the Empulse is able to translate its 90 Nm (66 lb-ft) of electric motor torque to over 880Nm (650 ft-lbs) at the rear wheel in first gear. The Hi-Perm-Mag motor integrated in the IET™ powertrain gives the bike an acceleration from 0 – 100 km/h in 5,5 seconds, enough forward thrust to relegate direct-drive competitors to the rear view mirrors and compel the motorcycling press to compare the substantial performance to that of 650cc twin class motorcycles.
Of course performance isn’t everything, and so the Empulse also boasts an impressive 438 MPGe (MPG electric equivalency) (.54 litre/100km-e) fuel economy, making the Empulse a smart move from a cost of ownership perspective as one of the cheapest motorcycles on the planet to refuel.
The patented IET™ system for the Brammo Empulse is manufactured in the IET plant in Umbertide, Italy.
