Getting a sports bike. Horsepower question?

[Jake1]

At the dealer I work at we have a 2006 GSXR600 with 272 miles. Mint condition. Or a 2009 ZX6R Ninja with 1117 miles in mint shape. I personally prefer the GSXR in every way, however being its older and the ZX6R was revamped in 09, what kind of horsepower difference is there? I've had a few bikes so I'm no novice. But I can't find anything anywhere about the power differences. And the people I ride with all have newer GSXRS, R6's and Ninjas so I wanna be able to keep up. Another option I have is an 04 CBR1000RR with 3009 miles. I just don't care for Hondas much. But anyways, will the GSXR be able to hold up with the newer 600's?

You seem to have a lot of re-wound mile-o-meters or have 'they' been all the way round and started again?
