2012 Brammo Empulse R Specifications

Wow! 54 Horsepower is pretty impressive. The torque is amazing too. Enough power for hooligans but not enough to hang with the super bikes. If you ask me, this is the perfect in town bike. I would also use it to commute to work even though my work is only 8 miles away. Plus I can only imagine the ‘What is that’ looks on riders faces at the local motorcycle meetups.

If I do get one of these bad boys I better be ready to defend its silent exhaust note and its relatively low power/range. But hey its the price we pay to advance technology, this is the beginning of what is to come. People that pay extra for less right now can justify it by the gas savings, which will hopefully push battery technology to the next level.

I honestly feel like Brammo took their time to do it right. Zero may makes a good bike too but if I had to choose it would be an Empulse all the way!


Brammo Empulse vs Zero S ZF9

They are decently even all the way around but the empulse has 2 fun factors the S does not have:

-6 gear transmission

-a top speed of over 100mph

The brammo also has a nice fat 180 rear wheel compared to the dinky Zero’s 130.

Zero does not claim any horsepower that I can find, but I am guessing the Brammo Empulse has it easily beat in the power department. I will see if I can scrap up some more info on this. Comparatively I think I am biased on Brammo Empulse’s side because is it so close to an actual streetfighter that could be accepted in the motorcycle community. By looking at the specs, the Zero S seems more like a big toy to me. But once again this is speculation, without seeing them and riding both of them side by side.

What I do know is that the power and low end torque delivery is close to my friends Kawasaki ER-6N that is an absolute BLAST to ride around town even though it gets snickered at on the track. I am not a track rider personally, but I do enjoy ripping up the pavement and this bike has no problem fitting the streetfighter profile. Big Grin.
