Don't really have much to add to the conversation, pretty much agree with everyone else's observations, good and bad. I have 43k+ miles on mine, so far no major issues.
Fork seal leak, steering bearing loose (from delivery), oil fill plug broke (Yamaha tech), front brake switch (recall), starter replaced (factory tech bulletin), all fixed under warranty
Gas cap cover got stuck closed while on a cross country trip, finally finagled it open, removed the latch so it wouldn't get stuck again and rode to my destination with painters tape holding the cover closed. Found a shop and they took it all apart, cleaned things up, lubed it lightly and it's been ok since. YES warranty covered.
Same trip, the heel/toe shifter fell apart when I was in Wyoming. All the pieces stayed with the bike and I was able to put it all back together in the parking lot. I think the bolt that holds things together is too short, but I probably should have used more loc-tite. Replaced with longer bolt and extra loc-tite when I got home and no problems since.
Left side saddle bag lid got stuck closed. Shop wound up sawing a hole in the lid, ran around with duct tape over the hole while parts came in. Pieces of the lock got lost during all this so the lid and lock were replaced. Thus I had two keys for a time. Got the old lock from dealer after repairs were completed and figured out how move the old lock assembly to the new lid and now back to one key. Disappointed in my local shop for not being able to figure that one out. Oh well. YES warranty covered.
Dashboard components have never fit correctly (finally gave up and learned to live with it).
I've had to replace a few of the plastic and chromed plastic parts due to road/animal hazards, but those things happen.
I've been running the tires at around 40-41 PSI and getting poor tread life from the OEM Bridgestones. At the last rear tire change I decided to drop the pressure to 38 and it appears tread life is better, won't know for sure for a few thousand more miles. I was changing the rear at 6-7k, front a little better. I'm now running an Avon Chrome on front, far more expensive than the OEM but I believe it is wearing better as well.
I recommend adding the lower wind deflectors to help with engine heat management. They are easy to install if you have basic tools and mechanical skill. Biggest trick is figuring out how to get the plastics off....
I really like riding the beast around, but I mostly just cruise along. I've been to 100 MPH one time and it ran smooth enough I didn't realize how fast I was going until I looked at the digital speedo and said " probably should slow down some". Wife loves the passenger seat/backrest and seat heater. She has used her heater extensively, I think I've had the driver's heat on twice, maybe. I use the heated grips a little more, sure nice to have in case you need it.
I think you'll enjoy the bike and it is an eye-turner. Love that blue.
