I had a 919 and loved everything about it. I put many happy miles on it with no problems,and sold it to a guy who was replacing a 90k-mile 919. I loved the whine of the engine, the color, the fit, everything. Some people say they're underpowered, but mine was stock and would take off from a stop fast enough to blind me momentarily.
That's all I gots to say.
