Try this... find a guy with a gixxer 1000 and do a drag from stop. I almost guarantee if you can ride your 6R you'll beat 'em most of the time unless you're running for 1/2 mile or more...
Thing is, even IF the guy can control the bike well enough to keep the front from lifting, he's so excited about not letting a 600 beat him, he'll be overaggressive and force it up anyway. Of course, there are riders out there who CAN really handle a gixxer 1k, but they're pretty few and far between. 'swhy I love 600's so much, just ABUSE that clutch and scream it out to a good lead on those big bore beasts. I do pretty well against them for short races (typical 1/4 mile go's)...
Our regular riding group consists of 4 ZX6R's, a 954 honda, an RC51, 2 R6's, 2 CBR 600's, a Gixxer 1000, a Gixxer 750, a TL1000R, and a VFR honda. One guy on an R6 weighs 135lbs, so he's tough to beat, but outside of that, they can all run pretty tight. That's the fun of motorcycling ain't it?
