I have had my green/black 150 for about a month now and love it. The color isn't very photogenic; pictures just don't do it justice. In real life it looks very good. I just got to 600 miles yesterday, officially breaking in the engine and got it up to 63 (according to the speedometer) I will take my GPS along next time to see how accurate that is.
Aside from wanting to get a bigger windshield, I've ordered some green reflective rim tape and helmet decals to make me more visible at night. I'd also like to get a storage bin on the back, maybe even saddle compartments. Does anyone recommend a particular brand?
