I think the 05 chopper wheels are the best damn wheels BDM has ever put out, especially if you chrome them.
I love my K9 but if I could go back in time and re-live my purchase, I'm not so sure I would be riding a k9 off the lot. Those choppers can flat out haul ass and maneuver. Doesn't take as much muscle to push them through corners and you get a bit more ground clearance.
Random trivia here, the k9s were so successful in 06 that Ridgeback orders dropped dramatically. The factory was stuck with a bunch of 06 Ridgeback wheels, production orders for K9s were through the roof, that is why the wheels switched mid year. That was what my dealer told me at the time anyway.
