Looks great and reminiscent of the Laverda from the early '70's, including the seat that only fits a jockey.



That looks like a fun ride though, for whoever might fit in!

Even more so BB.
Helmut's has a bit of the Ducati 750 Imola green frame about it too. Which came first?



Influences from loads of places.

It looks like the Boxermetal bike is taller than stock?

A bit of Googling tells me both bikes were raced in 1972... and won (?) perhaps different classes. The Ducati design was started in 1970: http://en.wikipedia.org/wiki/Ducati_750_Imola_Desmo : Perhaps BMW got some inspiration from the Italian effort? http://www.returnofthecaferacers.com...met-dahne.html

Man, that thing is awesome. It's a great juxtaposition of modified simplicity. Very minimal, tasteful, and beautiful!

Engine is rotated upwards, allowing more ride height in the rear (ie, swingarm points more downward). Along with the modified frame, it provides a racier stance, and room for the exhaust.

I was going to do this to my build, but I didn't want to fabricate an exhaust. Sticking with my 2:1 Luftmeister.

So the motor was rotated upward in the front, to make the swingarm aim more downward? And that was done to create more room under the seat for the exhaust?

Another benefit would be increased lean angle due to the cylinders being higher.

Ah. So that's why Diablo said that it's a "racier" stance. Makes sense.

There is a fine line, though, isn't there? I mean, if a bike is set up with a taller stance, at some point the advantages of a greater lean angle would be offset by the disadvantages of a higher center of gravity, right?

The angle of the swinging arm is determined by the rear shocks, not the angle of the engine.
It could be the the engine is raised ( rotated if you like) to make the transmission line up better with the drive shaft after the shocks have been lengthened, but moving the engine has no effect on the angle of the swinging arm.
