I mounted this one on my bike (k3 nekid 650) for winter...

(it looks bigger in the pic that in real life... don't forget to take into account what i looks like w/a rider to scale the size)
The best thing about it is the adjustable angle. If i'm wanting to hug the bike/ride upright, it can be adjusted accordingly. the install was easy too... mines perfect, took 15 minutes and i was already 1 bottle of wine into the evening when i started.
Another perk... it pop's on and off the bike (after the original install) in <1min with 2 thumb screws....
