BMW models with direct shaft drive and horizontally opposed twin pots are better for safety in several ways.

Lower centre of gravity, some "extra" leg protection in sideswipes | converging hits on roundabouts (from the pots and pot crash bar protectors), and zero chance of chain wear with better direct power pickup | engine braking from the shaft.

These are all grounds for some heated debate wherever two wheels gather, but I'll swear by them.
