2003 GSX-R600, bought it new, now has almost 30k miles. It's my track hack.
Mods:
Micron Exhaust, K&N, Remapped FI, Steel Braided Lines, EBC HH pads, Race Tech Fork Internals, Race Tech Rebuilt shock, both sprung for my weight, double bubble screen, ValterMoto Rear sets, ERC Stator cover, Woodcraft Frame sliders.
The suspension stuff wasn't cheap but it was the best money I ever spent on my bike.
2004 KTM 625SMC, 6k miles, track duty, street hooligan.
Gutted exhaust and airbox, that's it (Oh and a luggage rack, 'cause I'm effed in the head like that). It already has full WP suspension, Brembo monobloc brakes, steel braided lines etc. Love/Hate this bike, I'm working on it when I'm not riding it. It's the most fun I've ever had on two wheels, but it's also about ten times the work of the GSXR.

Nice shot of the luggage rack
