Theres a dealer that has a demo that me my dad and a friend went to test ride on yesterday.
Overall: A very, very sexy bike. Extremely narrow and light feeling (weights about the same as a rr) but more flickable. Pretty nice power band and a good strong pull through almost the whole tach. The shift lights are a nice touch (about 4 leds that light up incrimentally sp? till redline not just one at redline). The sound is unique but nice. Its sort of a high performance import car kind of sound, a little deeper than a 4 but still with a high pitch (nothing like a twin).
My only real complaints were that the rear tire would skurt when downshifting hard even with good tires and blipping the throttle, and that the throttle is extremely light and loose making it easy to acidentally goose it when hitting a bump or possibly give it too much gas while mid wheelie (at least for the unexperienced such as myself).
I didnt get to take it on any turns but from swerving from lane to lane on an open road it felt very steady and easy to control. Like I said even though the bike weights basically the same as the rr it felt much lighter and flickable. The bike actually felt a little to light in the front for my liking. As I would get on it the front tire would float and give a little shake but overall nothing serious.
In a straight I put a quick 2 bikes and a steady pull on my dad riding my 05 rr with a s/o (we weight the same...my dad isnt totally use to my bike and that was the very first time being on the 675 so the handicap I would say was about the same)
Seriously, other than the fact that parts/labor may be a little harder to come across and more expensive this bike is awesome. I am actually considering trading mine 05 rr in (seriously). I would by no means be embarrassed to sport that bike in a crowd of all jap bikes. It's sexy, unique, and precise. An aftermarket stabilizer would give me a better peace of mind, and Im sure the throttle can be adjusted.
I tell your friend go for it! Ride one if he gets an opportunity, but go for it.
Sorry if things are a little hard to read, Im tired but I hope you get the drift. lol
