This has been a very reliable bike. Parts are very expensive, and dealership service is hit or miss. With luck, you can find an independent mechanic (often cross-trained on Ducati) to save some expense. Very easy to perform basic maintenance (oil change, brake pad replacement, etc.) at home. Air filter is a total pain to access, though.
I have Two Brothers exhaust pipes, which make this bike loud enough to set off car alarms. They also make this bike faster than my father's stock Trophy 1200. The Trophy doesn't accelerate, it just warps between your current speed and the speed you want. Tremendous torque and roll-on power at any legal speed. Six speeds, and the ratios are pretty well spaced with stock sprocket sizes.
Have maxed this bike out at 130 mph indicated (speedo reads about 10% high), with plenty of throttle left.
Used to get 38-42 mpg according to odometer, whether city or highway, and now find myself getting 36-40 mpg. The bike prefers a higher octane gas, but I use regular unleaded any time but summer.
The Trophy runs kind of hot. Use Water Wetter and more water-biased blends of coolant (70 water/30 coolant) to make it run cooler.
Blinker lights on dashboard impossible to see in full sunlight.
Stock seat is not very comfortable, but I have put 10 hour days on this bike, comfortable the whole time. No trouble with vibrations; bar end weights are stock.
Locking, removable hard bags hold a lot; I once fit $80 worth of bulky groceries in/on the bike. A top box can be found, which holds almost twice the volume as one hard bag.
Seat height is high, but perfect for me with a 34" inseam. This is a top-heavy bike, and is easy to drop in the driveway. Not unmanageable, though - I have ridden 100 miles or so on dirt roads 'not recommended for passenger cars'.
On a bike that can easily do 600 miles a day, I'd prefer to have shaft drive.
There aren't many aftermarket options, but you can find windshields, bar risers, and seats from several sources.
This bike is gorgeous from any angle. It's also pretty unique - I have only seen 4 or 5 others on the road, ever.
