I've had mine for over a year now. It's been a great bike. I wish BD had offered the CF fork when I purchased mine.

So far, I've:

1. Stripped the clear coat and removed all decals and polished the aluminum frame
2. Swapped out the stock drops (they're crappy) for a Profile T2 bullhorn.
3. Swapped stock wheels/tires for a set of dp18's. I may polish the front wheel in the future. The rear one was a pita to do and i'm not looking forward to doing anymore in the near future.
4. water cage.

Surprisingly, the stock seats are pretty comfortable. I'll replace it when it starts wearing out.
