But there are significant changes, including a longer swingarm and beefed-up frame to handle the 988cc engine's power. (Why 988cc and not 998 like the R1? Proposed changes for GP racebikes would make four-strokes of up to 990cc eligible to battle the current 500cc smokers.) Rumors suggest more than 160 horsepower at the crank (say, 145 at the rear wheel) and a dry weight of 375 pounds. If you size up from the existing 750 (which weighs a mere 426 pounds wet), it's possible the 1000 could undercut the CBR929RR (434 pounds wet) and YZF-R1 (443 pounds wet) substantially.
