New High Output Twin Cam 103B™ Engine Power Asking riders if they’d like more power is like asking them “Would you like more beer in the pitcher?” when they've reached the end of a long day tearing up the roads. Everybody wants it, and the High Output Twin Cam 103B™ engine is 103 cubic inches of Harley-Davidson V-Twin you can rely on to deliver. The airbox increases intake airflow and the cam optimizes phase and duration. The result: better low-end torque and faster 60 to 80 mph 5th gear roll-on. In the tradition of the legendary Harley iron that came before it, the High Output Twin Cam 103B™ engine is once again raising the bar for the feeling an engine delivers to the left
