I have to say if you want an ergonomic (for teh rider) bike avoid BMW's.
the foot pegs are not opposite one another but the right one is several inches behind the left. This induces a sort of twist in your spine. This effectively means your right arm needs to be longerthan your left to have equal reach on the bars.
The gear and brake pedals are too close to the cylinders and their positions compromised by their proximity. You cant lift your foot and stomp on the rear brake but have to wriggle it under the cylinder and carburrettor to push down with ankle action only. To get around this they have lifted the engine and gearbox up o they are now above the wheel spindles in order to create room under the cylinders for your feet. ( albeit still at odd distances). This makes the quarter ton plus bike top heavy.
Every other bike I have had the petrol lever always had a pointer pointing to the off/open inscribed on the tap. The bmw uses the lever itself to point to the position, not the pointer.
the light switch also uses the switch handle to point to the function, instead of the pointer end.
However the machinery works, but nowhere on the bike will you find any compromise where the riders ergonomics won out over the engineers preferred option.
