Brammo's Empulse R leapfrogs the Zero S with a 100 mph 121 mile range electric motorcycle
As promised with last weeks video teaser release, Electric Motorcycle manufacturer Brammo announced today the specifications for the upcoming Empulse and Empulse R electric sport bikes, with the official unveiling still slated for May 8 in Los Angeles. As expected the specs leapfrog those of the top bike from Brammo's main competitor, Zero Motorcycles, with delivering in the Empulse R a 100+ miles/hr electric motorcycle, with a 121 miles range (city) and an integrated J1772 charging port for a 3 hour recharge time from empty, making 200+ mile a day trips possible.
Brammo will be unveiling two bikes on May 8, the Empulse and Empulse R. The spec sheet released by Brammo are for the Empulse R, leaving the Empulse a bit of a mystery at the moment.
The Brammo Empulse R electric motorcycle, going by the specs released by Brammo, is now the most powerful bike in its class. Of course, this is just a game of leapfrog, because Zero is going to announce something amazing this fall for that company's 2013 lineup. At the moment Brammo is ahead offering a 100+ miles/hr top speed, city range of 121 miles, highway range of 56 miles and a combined range of 77 miles. The Zero S ZF9 has a top speed of 88 miles/hr, city range of 114 miles, and a combined range of 66 miles. The difference appears to be that the Brammo Empulse R has a larger battery pack, 9.31 kilowatt-hours (nominal) versus the 7.9 kilowatt-hours (nominal) pack on the Zero S ZF9.
The slightly longer range for the Brammo Empulse R over the Zero S ZF9 simply reflects a slightly larger battery pack. However there is an interesting side note in comparing the spec sheets. Because Zero reports the highway range as 66 miles versus Brammo's highway range of 56 miles, the first reaction is a "huh". The larger battery pack should give a longer range, but the numbers don't match the expectations, leading to confusion. Clarity sometimes comes when you stare long enough at the footnotes. In this case we learn that the test procedure Zero used to determine the 66 mile range on the Zero S ZF9 is identical to the test procedure Brammo used to determine the combined range of 77 miles. That is, Brammo's test procedure for the highway spec is the "Constant Speed Riding Range Test Procedure for Electric Motorcycles" which uses a constant 70 miles/hr speed. Zero's test procedure for the highway spec is the constant 70 miles/hr speed, averaged with the results of the city speed. Zero's highway test procedure is the same test procedure Brammo uses for the combined range. But lets not spend too long in the footnotes, that's boring.
The Empulse R weighs in at 440 lbs curb weight (200kg) and a cargo capacity of 365 lbs (165 kg), making it a hundred pounds heavier than the Zero S ZF9. The frame is an all aluminum fabricated by Accossato in Italy, and comes equipped with Marzocchi forks in the front, Sachs shocks in the rear, Marchesini wheels front and rear, and Brembo disc brakes front and rear.
