Copyright 2002, Roadracing World Publishing, Inc.<BR><BR>By David Swarts<BR><BR>Over the span of eight months and six rounds of the 2001 Formula USA National Road Race Series, Blackmans Aprilia took its RSV1000R Mille R racebikes from being the slowest machines on the racetrack to being the fastest bikes in the 145-horsepower Unlimited Superbike class. Thanks to parts developed by Crew Chief Bill Himmelsbach, the Blackmans Aprilias went from making in the neighborhood of 110-115 horsepower as measured at the rear wheel to well over 140 horsepower. Now Blackmans is offering the same parts to the public.<BR><BR>Blackman's Stage One kit is designed to increase the output of an Aprilia Mille or Mille R by 10 rear-wheel horsepower. The $1985 kit includes 97mm high-compression pistons, Stage One cams, re-worked cylinder heads, 54mm throttle bodies and a fuel pressure modifier.<BR><BR>The $4371 Stage Two kit is said to be good for 20 extra horsepower at the rear wheel.
