R3T's a great bikes. You'll have a unique bike that's water cooled-a huge plus in FLA. Sure, it's warm in the summer-sitting on any motor is-but not as much as 95% of the air-cooled bikes you can buy.
The real difference is in the pull of the motor. There are plenty of two lane roads down there where ma and pa go 20 under! the R3 family of bikes lets the rider make a pass that many others cannot in a safe manor. This cannot be overlooked as it's a huge factor in "real world" riding.
Like 100% of new bikes, and thanks to the EPA, a Power commander or Tuneboy will improve the bike be a noticeable measure. EVERY bike is too lean which contributes to the heat, and many other issues. No, you don't have to-but it sure helps. Triumph also offers pipes and a tune for that bike which, for factory parts, works quite well and is goof-proof.
Another factor is the extended maintenance chart. Oil only every 10,000, valves at 12,000 miles, and you are about done. No maintenance with the shaft, no belt tension to check or align, not to mention how well the handle. This bike won the "battle of the baggers" done by CycleWorld-you can see for yourself on their website.
Finally, the bike never knows if you have a pillion, or loaded it down, or there is a 50 mph headwind. It's got power to spare!
