Why are SW Motech crash bars asymetrical?

[pdedse]

I have SW Motech bars on my bike, and did several posts on the mounting bolt torque specs, bolts to use, and reasons the for both. The bars are symmetrical. If you measure from the frame to the outside face of the crash bars on both sides, they are both an equal distance from the frame. What makes the bars look asymmetrical is that the engine casing is wider on the left side.

Funny how sometimes it's hard to spot the obvious. A few posts prior I was wondering if the difference had to do with less lean angle, but yeah, even just by looking from above you can tell the left side casing is wider. Never noticed that before.
