A BMW Rep rode a charcoal grey S1000 to the Mira Mesa Bike night last night with some young female play toy in order to get attention and interest in the bike, as if he needed to.

So the guy went to a press release about the bike with the BMW designers and learned about the design cues on the bodywork and why it looks so funky. SO here is what I learned.

The reason why the side fairings are different has to do with pressure changes behind the fairings. They used wind tunnel testing and advice from Formula 1 engineers to learn how air pressure works inside the bodywork. They found that by using the fin design on the right side, they could create slightly positive yet stagnant air that would resist a vacuum on that side of the bike. They then figured out that if they used a large gaped opening on the other side, it would work like a super vacuum and pull air very efficiently. By combining the 2 designs on the bike, they worked out this sort of super flow of air that would whip past the front of the motor and the radiator. The right side would charge the air pressure and the left side would pull the air from the right constantly over the motor and out the left side of the bike, which also is designed to dump out away from the riders body.

Now, the headlights. They wanted the bike to have a Suzuka Endurance racing feel to the front headlight assembly. Much like how race bikes that run 8 hours at Suzuka usually get a big hole drilled into the fairings and a PIAA light scewed into place, that's how they wanted the front headlight on the right to look. They knew that the left headlight would get covered by a number block, so they left it looking standard as it would get deleted anyway. Also, by not using the large headlight from the left on the right side, they saved a pound and a half from the bike's total weight. Thus, they get an endurance racing headlight setup right out the box with the left headlight easily deleted for a number plate.

The windscreen on the bike dips into the ram air molding on the front to help provide a blade of plastic that cuts through incoming air and creates a swirling effect to the air as it enters the airbox. This design cue in the wind tunnel supposedly added 7hp at top speed.

The bodywork of the bike, made from plastic, is also varying in thickness across the whole design. In order to save weight, the bike's bodywork is thick where it needs to be, and paper-thin when it doesn't have to be strong. They, again, saved a fair amount of weight in doing this. All of it adds up to low weight and a better power-to-weight ratio.

Now that I know all of the design ideas were done to shave weight, provide more efficient design for power and cooling, and to make the bike as amazing as possible. I like it.

thanks for the info. I personally loved the look already, to know that it is all functional as well is just icing on the cake.

I had mixed emotions about the bodywork design thinking they were just trying to take a stab at wild styling, but once I learned that each and every weird shape had a purpose, I quickly learned to like it. Wild form with function always takes honors in my book.

Wow that's awesome post man! Thanks for the useful info :beer

It's always interesting to know about the reasons behind the less orthodox design decisions on any piece of machinery!

Would any rider ever notice any of these design elements though? Most of it sounds pretty gimmicky. Did you get any pictures of the bike?

And for everyone that doesn't like the headlights and haven't seen the bike in person. Wait, this is one of those designed that you can't see from a picture. From the pictures, I was like "WTF? is up with that?" Looked weird and stuff, but when I saw it in person it had that "What the F*ck are you lookin at" look... It was cool.

There are a lot of things out there people add to their bikes to make the go faster, but end the end. They do not notice it. For it's such a small gain (exhaust) it's almost worthless.

the more I look at the bike the more I like the wacky headlights, it actually has a pretty badass look to the front.

Only BMW on the westcoast? There are two that frequent a shop here

On topic, I sat on it before and it is unbelievably light. The rep told me its only a few pounds heavier then a stock r6

It's gonna be trouble
