Right on schedule, Brammo has released the technical specifications of the Brammo Empulse & Brammo Empulse R electric street bikes. Featuring a 54hp water-cooled Permanent Magnet AC (PMAC) motor, the Empulse will come with a 10 kWh (9.3 kWh nominal) battery pack, and of course the Oregonian company’s six-speed gearbox. With fully-adjustable Marzoochi front forks, a fully-adjustable Sachs rear shock, Brembo brakes, & Marchesini wheels, Brammo has included some nice kit on the Empulse, though the company hasn’t tipped off to what the “R” designation will mean for consumers.

Our best guess is the Brammo Empulse will be a naked version that is very similar to the Empulse prototype we’ve seen from day one, with some cosmetic updates of course, while the Brammo Empulse R will be a fully-faired sport bike that strikes a similar line to the Brammo Empulse RR electric race bike.

Asphalt & Rubber‘s Bothan spies report that the gearbox works incredibly well, allowing the Empulse to operate just like a standard street bike with shifting and gearing control. There’s still some debate as to whether electrics need trasmissions, let alone close-ratio six-speed transmissions, but we’ll leave that debate for another day.

Still not releasing any images of the new Empulse and Empulse R, Brammo will be taking the wraps off its latest bike on May 8th at an event to be held in Los Angeles. The unveiling will also be live-streamed on the web as well. Click after the jump for the full technical specifications of the 2012 Brammo Empulse R.

  • MSRP?

  • @Tyler – Prices released on May 8, when they reveal the production models.

  • Keith

    urban bomber ONLY…sorry no thankyou. The short ride where I live is 30miles…not a plug in station anywhere. Want to go to wal-mart? Nearest one is 130miles.

    And then you tell me the batter wears out in roughly (very) less than 8 years? I think it’s not ready for anyone but a hipster.

  • Ervgopwr

    Not a hipster here, but an urban liver, and absolutely no need to go to walmart. But count me as intersted in the development and progression of these machines. I may not be an early adopter, but certainly it’s on my radar for the future of two-wheeled (power) riding. I pedal most of the time anyway.

  • Keith, Li+ battery packs like this are typically being rated to last 300,000+ miles. And hipster? What’s hipster about electric motorcycles?

  • Jeram

    300,000 miles is alot longer than most motorcycle internal combustion engines will last.

  • Jeram

    I for one would be more inclined to look at one of these bikes if there was the promise that as battery technology increases that they will make upgraded packs for them.

    for instace, by the time I do 300,000 miles and my battery is ready for replacement, is Brammo still going exist sell me a new 10 yr old technology battery, and further more are they going to be able to supply an updated battery with the latest technology.

  • Richard Gozinya

    There’s that Jeram, plus no oil changes, or tune ups. And there’s already people figuring out ways to hotrod electric vehicles, so there’s that. I don’t think EVs are quite on par with ICE’s just yet, but they’re getting there, faster and faster. And hipsters? Really?

    I’d tell you what hipsters really ride, but you’ve probably never heard of it.

  • Richard Gozinya

    Jeram, I’m guessing battery upgrades would cost you. It’s probably not as simple as just plugging in a new battery, there’s stuff to do with the power controller as well. Like when you put aftermarket pipes on a bike, ECU needs to be adjusted to properly deal with the new air flow. A new battery would require some adjusting as well. Guess the point is, it’s not going to be free.

  • JohnMc

    Please tell me the forks are Marzocchi, and not Marzoochi…I jest.

  • Ryan

    Looks sweet, but I may tend to side with the dissenters on this one. My commute is 90 miles one way. Unless I was rich or a hipster, there’s no way an electric would ever be feasible. That being said, I think electric systems are much better suited to motorcycles than cars, so I hope the development continues to progress and go well.

  • Wait, when did Ural start making electric motorcycles?

  • Minibull

    You misspelt “Transmission”


  • frogy6

    So for a proper spin the battery will last 54 miles? That’s shit, and that’s if you don’t go 70

  • @frogy6 – Where did you get that idea? Granted, range, when compared to ICE bikes, is going to be frustrating until some major battery advancement occurs. But the spec sheet above indicates that the bike can go 56 miles at a sustained speed of 70 mph. I’m not even sure where you get your “54 miles” figure, and, obviously, I have no idea what a “proper spin” means to you.

  • frogy6

    Apologys I ment 56 miles, a Sunday spin I’ll burn at least a tank of petrol, so at least 100 miles. Apart from some main roads, many back roads a constant 70 mph is no problem. So it wouldn’t even do half what’s considered a standard spin in Ireland.

  • Keith

    300,000 miles On a Lipoly or LiFe packe does NOT equal 1,500 charges and 80% max capcity means you have 20% less range.

    Your argument is not valid.

  • frogy6

    How many miles before the battery starts to deteriorate, like is it after 50k it starts or 300k
    Or what % will ya end up with at 100k/200k/300k

  • Above comments are hilarious. Conjecture upon conjecture… just for the sake I think…

  • mxs

    It’s very misleading to relate battery lifespan (to hold 100% charge) with a mileage figure on its own. Any pack can do 300K …. there has to be somewhere in the equation how many charges does that account for. If I charge the battery 1500 x after 30 miles traveled, the battery only lasted 45K while being able to give 100% performance …. most people will view that as not such a great deal, considering the cost of the new batteries this time around.

    I like the specs of the other bike parts, but anything regarding the battery is unfortunately not so great news (as expected). It’s the same old, until someone comes up with new technology/materials it will continue to be the same tune …. expensive and heavy due to the battery pack.

    But I applaud them for the efforts and I wish I could support the development in some way ….

  • What happens when the Brammos, Missions, and others with NO distribution channel have to compete with Honda and a superior product, distribution channel, and economies of scale?
    What will these companies do in the face of competition from far superior…. companies?
    They will etch their name in the history books of motor vehicle manufacturing, which is hopefully worth something. But it’s not, unfortunately, worth money.

  • Mr. X, Polaris owns a good stake in Brammo. If this bike takes off, a dealer network shouldn’t be a problem.

    As far as the Battery pack. the 300,000 miles is the estimated mileage life of Zero’s 9kWhr pack. Brammo is using a different chemistry. They claim 1500 cycles (one cycle would be a full 9.31kwh used, not every time you plug it in) to 80% capacity. Using the 77 mile range for combined highway/urban usage, and nominal capacity (9.31kWh), you get 115,500 miles to 80%. 84,000 if you drive 70 the instant you take off until you stop, or 181,500 if all you do is urban commuting. By the time you wear the pack out (how many of you have put over 100,000 on a motorcycle, really) Brammo may not offer a replacement pack, but there will be an aftermarket company that will, with better batteries no less, and the software updates needed for the controller and BMS. If not, let me know and I’ll start one. But really, by then the rest of the bike may just plum be worn out. I think at this point the argument against the reliability of battery packs is silly. Especially when compared to engine life of an ICE bike, and the costs of having a motor and transmission rebuilt. But, it still remains to be seen.

  • ttxgpfan, actually the Zero and Empulse are using very similar cells to my knowledge (NCM prismatics from what I have seen published… I’m sure someone will correct me if I’m wrong), though the Enertia uses different ones. The two companies choose to rate things differently, but real world life cycle should be quite similar between them. The Empulse will stress the batteries more due to it’s higher motor output, but it also has about 15% more capacity (9.3 vs. 7.9) which reduces the stress proportionately. It’s also worth noting that a charging from a partial discharge doesn’t “count” as a cycle in the rated life. It’s actually really good for the battery. That is, if you only discharged it halfway each time, you would have MUCH more than half your battery life after 1500 cycles.

  • protomech

    @Marc F

    The Zero and the Empulse both use NMC pouch cells, Zero uses 20 Ah EIG pouches and Brammo uses 10 Ah pouches of an unknown make. Same pouches (presumably) in the Empulse (28s9p) and the Enertia Plus (24s7p) .. and quite possibly the Empulse RR race bike as well (probably 84s2p).

  • @protomech
    Awesome, thanks for the added info. Exactly what I have seen for Zero and Empulse, except I could have sworn shots of the Enertia Plus battery with the top unfastened showed cylindricals… maybe that was a deceptive view or an experimental prototype?

  • mxs

    Something doesn’t make sense …. whatever battery chemistry they are using, unless there’s an unpublished breakthrough in recent times, if a battery is topped up every night (don’t say you don’t have to, because most people will do …otherwise who wants to be left stranded if I decide to take a different route home), the battery will suffer from what is normally known as a memory loss (even though manufacturers always say that it doesn’t exist). If it didn’t, all these lithium batteries used in various devices would be able to keep 100% of their charge for as long as advertised. None of them do. So whether a manufacturer calls it a full cycle or not, I don’t really care, because my battery will sooner or later not be good for 60 clicks, but rather only 40, and after another who knows how many cycles it will drop to 30 …… or is there an actual evidence to suggest otherwise?

    Not arguing, just don’t like when I am being served too-good-to-be-true-cake without knowing who baked it.

  • Nickel cadmium batteries had the battery memory problem, not lithium ion batteries.

  • mxs

    Nickel cadmium batteries had the battery memory problem, not lithium ion batteries.
    What are you talking about? That is exactly the myth being spread without evidence proving otherwise …

    Every battery type has a life span, yet no manufacturer wants to truthfully talk about it (saying that battery will last 300K is like claiming that my fuel tank will last 500K …… the one thing I do know is that every time I put 12L of gasoline in my tank I get certain mileage and it doesn’t matter whether I fill up half empty every day or not).

    BTW your laptop, iPad, iPod whatever recent device does have a lithium ion battery in it. Ask yourself how long it took before the battery started to last a lot less than when bought new? Both my laptops started to seriously feel it within a year …

    I know you are excited about anything electric, but pls can we keep it a bit rationale?

  • @mxs Yes, every battery type has a life span. Your original comment, however, stated “if a battery is topped up every night (don’t say you don’t have to, because most people will do …otherwise who wants to be left stranded if I decide to take a different route home), the battery will suffer from what is normally known as a memory loss…” Memory loss, or memory effect, is something different than loss of capacity over time. Memory effect: http://en.wikipedia.org/wiki/Memory_effect . Both Zero and Brammo have been pretty clear about the useful life of their batteries – After the specified number of charge/discharge cycles, the batteries will only be holding about 80% of their charge when they were new. You can still use it, or you can replace them with whatever happens to be the newest, latest advances in battery chemistry.
