1) Power - It's great having the extra power vs. my GV250. The torque of the BA is impressive for a bike of this size. And the power to maintain highway speeds + more in the back pocket is good to help me stay out of harm's way on the freeway.
2) Sound - The aural experience is impressive. The stock pipes on the BA were nice but a little quiet, so I upgraded to the louder Triumph pipes, and the sound has a nice rumble to it, without being obnoxious.
3) Handling - This quality of Triumph bikes is well-known, and the handling on the BA belies the fact that it is a cruiser. It's no sport bike, but for a mid-size cruiser, it is very good.
4) Comfort - The seat is pretty comfortable for a stock seat. I had to have my GV250 seat worked on to add a gel insert to alleviate the pressure on my tailbone area. I don't think I will have to do this with the BA seat, although it wouldn't hurt (no pun intended), especially for longer rides.
5) Beauty - I think she has ton's of it! Up till now, I've been a "classic" cruiser fan, represented by bikes with heavily valanced, retro looking fenders, but recently started to like the more "custom" look, which the America falls into.
Now, some little oddities:
1) The forward controls took a bit to get used to for me - I am short in the legs, so at first I thought they would be too forward, but actually they are quite comfortable now.
2) The kickstand, like the controls, is placed more forward than on other bikes. I have to stretch a little to get at it, and luckily there's a tab on the kickstand which helps my boot to catch it when putting it up (putting it down is no problem). I think for someone shorter in the leg than me (I'm 5'8" with a 29" inseam), it could be a problem, although I have heard of shorter people being able to get at the kickstand. I had issues with the HD kickstands as well, so it could be my bodily configuration.
3) Fueling - this has been a challenge for me. The GV250 has a fairly large opening for the tank, and I could usually tell when I was getting close to the top of the tank. The BA's opening is smaller, so it's hard to tell how full the bike is, plus depending on the pump nozzle I tend to get more spray on this tank. The pumps with the vapor sleeve nozzles present the most difficulty for me. The older style of pump is no problem, especially if I fill slowly.
4) Tachometer - I think I have a faulty one. The BA doesn't come with a tach standard, but there is a space on the tank console to place either a clock or tach. I like having a tach, which I have on my GV250, so I had the dealer install this. One day, however, I seemed to be showing much higher rpm's than the sound of the engine would dictate. When I turned off the engine, it stayed at 2000 rpm instead of zero. Luckily for me, this issue in known in the Triumph forum, with an easy fix until I replace it tomorrow.
My overall impression is that this is a fantastic bike, and I am glad I made the decision to get some British iron!
