04 Ninja ZX6R 636!
I rode an 03 for almost 6 years. Still one of the best looking bikes on the road. I finally parted it out at 97k miles. Never once touched the motor besides standard preventative maintenance. That bike was still getting 35-40mpg even with nearly 100k miles on it.
Wow! 97K? That's insane! Only thing I've done is K&N air filter. Everything else is stock. Just got it off my boss last spring with 8000 on it. He was at least an inch away from chicken strips. I love this bike, quick, light, and corners great. Got it for a steal too.
