Agreed to ALL the above. Love the new cup holders, although I haven't seen the new lil glove box, it does sound like a great addition. As far as the suspension goes, I believe it is a matter of time and effort and adjusting it to what feels right for the type of riding you do. Keep in mind (at least on the EX models) you have 2 adjustments on each shock (compression and rebound with 6 different settings) plus your preload of each. 48 different settings plus preload adjustments gives you a lot of variables to deal with. The 2015 Air filters were junk, unfortunately i bought an extra one before I knew better and went with the UNI. Glad i didn't ride it off pavement before I switched it. 2015 still had some of the old thermoswitch ( fan switch ) in them. Went through 3 before I got a good one. Some complain about the stock tires not being very tough, I know I've punctured mine a few times. Again that too can be rider error, as I was running about 18-20lbs in them. No real issues since I dropped them down to 14 rears and 12 up front, some even going lower. 2015 still had the older style shocks with the "helper spring" on top of the main spring. (some reservoirs were getting rubbed) Dealer replaced mine under warranty.
Some of us get fogging in the headlights (yet again, depends on your environment).
As with anything "used" just use common sense, listen to it, drive it. Ask to see the air cleaner, and have them pull it off and look inside to make sure it isn't or hasn't sucked in dust. Look at the A Arm bushings, pull the A Arm back and forth make sure there is no play or rattling. Let it run until the fan comes on (should be 3 BARS).
