You’ll need it. Or at least a good set of braking hands—this latest RSV4 still producing a claimed 201 hp at 13,000 rpm and 85 pound-feet of torque at 10,500 rpm, despite now meeting Euro 4 emissions standards. New pistons are lighter and allow for less blow-by, connecting rods have a special treatment for reduced friction, and the valve springs are updated “in order to guarantee reliability during the heaviest operating loads,” Aprilia says. Maybe related, maybe not, but Aprilia has raised the rev limiter by 300 rpm, through a new ECU. The variable timing intake ducts have also been eliminated, Aprilia going on to say that the extended rev range renders them unnecessary.
