Don't electric motors lose power and torque the faster they rev? I always understood it as a different power curve (albeit one that starts at 100% torque at 0rpm) meaning it too could benefit from gears.

It could be worse.

Not sure how, but it could be.

Why do the curves cross at around 1200 rpm?

(ft-lb * RPM) / 5,252 = horsepower
just as
(Nm * RPM) / 9,549 = kilowatts

So they don't cross as such, it's that the graph is presented that way. Power measured here is a function of torque by RPM. That electric motor creates its highest torque down low, the torque dies off as the RPM increases. Horsepower in that function increases until it hits a point where the torque has reduced enough the horsepower will follow the torque down from then on.

They usually aren't. I actually can't think of an example where I've ever seen that to be the case.

I can upgrade whenever I want, I just need to get some time in a bigger bike before I take my QRide. Dad and I went out the other day and I was on his VF1000F-II, I'll probably upgrade in a month or two if I can find a bike by then.

Everything you said is true but according to Z3n (who's room mate bought one) wheelies just aren't going to happen. I can confirm the fool is otherwise capable of pulling a wheelie.



This guy's got it worked out, but I don't know about pulling it off on the heavier Empulse model. Should have released the Engage first.

No, but they are road-legal in the UK - Sikhs are specifically exempt from helmet laws. Interestingly if the turban is wrapped fairly loose and the wearers hair is in good condition the impact protection is actually equivalent to a CE-marked helmet (but doesn't cover enough of the head or give enough abrasion resistance to be granted CE approval) if it were a helmet.

I was just presenting my answer as a question because I wasn't sure if that's what nsaP was asking about specifically.

I saw something the other day that confused me:


Aren't those resevoir socks meant to keep the bouncing fluid in the front brake from being a distraction? Or are they for leaks?
Either way, bike was dumb.

Yes, but the stretched swingarm and 6 inch fork drop clearly says the owner doesnt care about the right way to do things

Front end slammed to reduce wheelies (for drag racing). Unless he limited suspension travel, that's going to put the fender crashing into the fairing at full bump.

The reservoir sock is used to protect the weak plastic of the reservoir from the sun. It's amusing that he covered the rear one (which doesn't need it) but ignored the front. I think he thinks it's a style thing.

Is this real? Why does it have a conventional fork and a suspiciously ducati looking headlight?

edit: there's no way that's an actual production BMW bike when it has almost none of their styling cues, wavy front rotors, circular conventional headlight etc.

Is that an "artist's conception"? I am not seeing their new liquid cooled wet clutch downdraft engine, a telelever setup on the front, nor the cross-pipe or gigantic catalyzer that should be there.

Design Corner - Bmw "R 1200 R Mystic" by Petit Motorcycle Crčation
December 13, 2012
After the photos appeared on the network, I thought the presentation of the new BMW roadster had been scheduled for the show in Milan this year.
The 90 years of the German will fall in 2013 and apparently the leaders of the house of Monaco chose not to take up room and visibility to the many innovations that have made ​​for the upcoming season.


Nicolas Petit, a French designer who have already had the opportunity to meet at the Cafe, has produced a series of sketches that prefigure the arrival of this naked will not replace the R 1200 R, but will propose a variant minimalist and essential.
The bike, which most likely will be equipped with the current boxer raffeddato air, it will be equipped with the famous Telelever suspension.


In the first picture below, used by BMW to celebrate the anniversary of his most famous engine, you can see a figure not very different from the version of Petit.
The arrival of this twin seems to revive the glories of R100 Mystic, naked classic Bavarian house produced beginning in the 90s, who has not had widespread.
