The BMW K models have a single sided swing arm, with a wheel Bevel Box. The single arm also houses the prop shaft. A neater mechanical solution at the wheel, but then you have the issue of the prop shaft angles (or just ignore it and plough it through the seat).

The K Bevel Box did have a habit of stripping its teeth needing replacement (even big manufacturers get it wrong)

The Honda GL1800 also use a single sided swing arm and wheel bevel box (as Larsen uses) and these are much more reliable, but again have the prop shaft issue.
