As a motorbike rider myself, I find this terrible. It obviously makes the whole bike more expensive as you have to integrate all the hardware, which can break down although you might have never used it. Isn't BMW going to do something like that with its cars, too?

A question that might arise from that: Say I don't use/buy a specific feature for the first X years and want to have it enabled after that. It then turns out that the hardware required for that is broken. Who's liable for that and has to pay?

In a classical scenario, I'd have sth. like a two year warranty on the newly integrated parts, but as those parts were integrated for the X years I've already owned the car/bike and the defect has just come up as they were activated now...
