I bought a lightly used (1700 miles) red '15 FJ-09 back in May, and have really enjoyed it for blasting around and commuting to work. I've added about 5k to the odo. Mine came with heated grips and factory saddle bags, so it is quite similar to the Tracer GT.
The upgrades show that Yamaha is listening to their customers by addressing most of the issues that FJ-09 owners are harping about. Storage, suspension and cruise control. It will be interesting, price wise, to see where the Tracer GT lines up. Will the price be close to the FJR?
I will be interested in seeing if the cruise control can be retrofitted to the older models. Other upgrades, such as the slipper clutch on the newer models have already been fitted.
The drain plug issue mentioned above has also already been addressed with a revised oil pan on newer models. And, like any good forum bunch, mods have been developed to lower the likelihood of the bash, along with several different skid plates.
As far as a LD mount, there are a few things I'm addressing. Passenger pegs were designed for 13 year old contortionists. Stock seat is crap (going to get some flavor of custom soon), original windshield offers little coverage, and I would love another gallon of gas! And, of course, it's chain drive. But with a bit of work, I think it will be decent for longer rides.
