The graph shows a substantial depression at 5000 rpm, but it's unnoticeable from the saddle. The Crossplane inline-four gets into the horsepower sooner than the Aprilia's V4, but it doesn't build as high and isn't sustained as long.

More legroom, a shorter reach to the bars and a well-padded seat go a long way toward making the R1 the bike of choice for longer rides. But when airflow slows, the underseat exhaust threatens to char-broil your rump roast.
