Blackmans Cycles Aprilia’s Michael Himmelsbach took his fourth win out of five F-USA National Road Race Series Unlimited GP rounds Saturday at Portland International Raceway and clinched his first four-stroke National Championship. Himmelsbach got a good start, pulled out a comfortable lead on his Pirelli-DOT-equipped RSV1000R, and won the race by four seconds over Edge Motorsports teammate of Michael Fitzpatrick and Greg Leffler, both on Suzuki GSX-R750s.
Penguin Racing School/Bitwrench Incorporated’s Jeff Wood needed one single point to clinch the GPRA/F-USA 250cc Grand Prix National Road Race Series Championship at Portland. So Wood decided to leave his Yamaha TZ250 at home and run his Aprilia Challenge Cup RS250 in Saturday’s 250cc Grand Prix at Portland to take seventh place, more than enough for 26-year-old Wood to capture his first National Championship.
Bridgestone/Speed Tune’s Ed Sorbo won the GPRA/F-USA 250cc Grand Prix race at Portland thanks in part to a 10 mph top speed advantage his Yamaha TZ250 had over the next-fastest machine. Patrick Dowd finished second in the race just in front of Kory Gill, Michael Ellsworth, and Roadracing World Editor John Ulrich.
