True, and the BMW flat twin is a good example. My 2007 R1200RT makes 110hp, and 92 ft-lb of torque, weighs near 600 lbs with seven gallons of fuel on board, can carry more than a full dresser Harley or Indian, even has shaft drive. But, it looks nothing like a Harley in any way, and it makes the hp and torque at least 3,000 rpm higher than a big V-twin. That is itself is a big challenge, as a typical big V-twin makes its HP and torque around 2800 rpm, which sells to the classic big V-twin buyer, LOTS of low end grunt, and lazy rumbling at highway speed.

Perhaps a better example is a Ducati V-twin Multistrada, making 113 hp and 71 ft-lb of torque, weighing only about 500 lbs, but again the HP and torque maxes out near 7.000 rpm, 2000 rpm higher than the typical power curve of a common big V-twin.
