The problem with technology on BMW bikes is that they are not putting technology into making them reliable. The complexity has increased, but the technology used to build the bikes has not kept pace like it has with the Japanese luxury cars. Where I notice this most is in the wiring harness. The Japanese use different plating for their connectors and better seals. I doubt this actually costs anything extra, they just pay more attention to these sorts of details. Compared to a modern Lexus, modern BMW car electronics seem almost crude in comparison. In general, all the seals on Japanese cars look and feel better made than on European cars. Taking to car mechanics, the Euro brands frequently come in with transmission and engine leaks. It is not nearly so common on Japanese cars. Overall, the Japanese have upgraded a lot of the little details that go into manufacturing a car where the Europeans spend more time on the design and feel of the car.
