I myself think I got a hell of a deal also.
The bike had a original sticker of $8,700 I paid $8,000 I also got the matching GSX-R SHOEI helmet for $200.
I had all of the other stuff from when I had my CBR.
I actually rode the new CBR 600RR and a buddies 636 the RR is much improved for 07 but lists at $9,500, the 636 felt like it had little more midrange but I never liked Ninjas. Hell I was die hard Honda but the GSX-R's seat height was more appealing.
I can't really comment on pricing. I'm not sure what the guys pay on the other forum I'm on. If you're on sportbikeworld or something like that forum, the guys I know go by, ghost, eEjeremy, Nexus or Nex, Kegs, Smirkingsoap, Applejacks and a few others.
I don't know. The bikes that a ridden on the forum I'm on are:
'03 GSX'R 650
'05 GSX'R 750(I believe)
'07 GSX'R 600(black, just like yours.)
'05 GSX'R 1000(Blue and White color scheme)
'07 CBR 600RR
'06 SV(I think?)
I love watching them talk about their bikes and take pictures and such. I'm very "envious" of some of them. I just couldn't trust myself.
There is quite the variety. There is even a guy with an older Cafe Racer or something like that, that he is restoring. Pretty badass.
