Look for dents in the rims, a sign of possible abuse, or a lot of fun being had. Look for missing spokes on the rear wheel, a sign of neglect. Look for any oily dust accumulation around the final drive, could be kind of normal, but needing attention. Brake pads could be real close to done. There's a weep hose on the right front of the motor, down low, fluid there is an indicator of a leaking water pump, or pump drive shaft seal. Some have run for years with a drip down there. Run the vin # by your dealership and make sure any recalls have been taken care of. A little early miles wise, but listen for an excessive rattle for the first five seconds or so on start up, being mindful that the motor is pretty noisy to begin with. I've got 90,000 on my '12. Eemsreno has over a 125,000 on his. There are many here at or over a 100k. They're great machines.
