Friend just picked one up (in Guldens Mustard yellow) last week, 4 days after I picked up my 06 636... A lot of nice extras on that bike like the tinted windscreen, stainless lines, Super Corsa Pro, and better adjustability on the shift light... It does lack the slipper cluch I beileve tho, and aftermarket parts are difficult to find and options are limited.
Comfort wise tho, its not much better than the plank of a seat on the CBR600RR....
