The suspension on the 09-12 models is very stiff compared to what most street riders actually need. The springs were changed in '13 to softer ones, along with mods to the fork valving. Compression is handled on one leg, rebound on the other. (That's the SFF, in the description.... Single function fork)
Honestly, the real challenge is finding a clean bike with few mods and regular maintenance at a price you want to pay. Mileage only matters if it hasn't been kept up with regular oil changes, and valve adjustments. Tires, replace with ~5K miles, chain and sprockets, ~15K miles. Battery may last 8 years or more, typically less.
Cosmetics get worse with miles and wear. Don't expect perfection.
