I just bought a 2005 GSX-R750 20th anniversary edition, with 11,600 miles and a "new" transmission. Selling price, including taxes and all the dealer add ons was just under $5500. Bought it from a well regarded dealer, with the bike being serviced there for last 5 years. The OEM sliders, and blue drive chain were the only items not on it as stock. The tires showed that the previous owner didn't really ride it as intended as evidenced by almost ZERO wear to anywhere but down the center of said tires, which had plenty of life left. It did have a tip over on the right side, as evidenced by the vertical scuffs on the bar end, front and back pegs, brake pedal and fork cap, no signs of any sliding witness marks or fairing damage. The bike went up for sale by the previous owner after it had a major transmission seizure. All the work, and new parts, new clutch plates, plus going through the engine to ensure no passing of scrap was covered by Suzuki under factory warranty after it was determined there was an extra side shim left in the transmission case at new assembly. It was proven after sending Suzuki photos of the entire trans laid out in sequence, and finding one extra shim that had no wear on either side of the larger pieces found in the case at disassembly. After looking it over for an hour, talking to the Sales manager, and the shop tech who did all the work, I tested it, and had to have it. And I have put on new sliders and a black seat sourced on line, very happy with these.
Good price? Too much? Your opinion may differ, but it has been flawless so far, and I have put 3000 miles on it, just did a 5 hour ride and found it to be REALLY comfortable, and an EFFIN' blast in every way. For that, I never thought about the $$$ again.
Also, I would like to profusely thank our US Gubbmint for subsidizing the majority of the full purchase price. I felt it was my patriotic duty to roll it right back into our economy!
