Take a bike like the Triumph Rocket III which has an inline triple cyl engine mounted longitudinally and uses a shaft drive. Would such a design still transfer power less efficiently to the wheel than a chain? My understanding has been that if the crank shaft of the engine and the drive shaft form a 90 degree angle then that is when you have more loss of efficiency of power transfer. In the example bike, the crank and drive shaft are parallel to each other.
