i have an 04 R6. i love it. it felt real comfortable for me and i had great results with it on the track. I have an Akra slip on, power commander and K&N filter. I really never was a huge Kawa fan, but you should compare the HP at the rear wheel, wet weight, ease of maintaining, and possibly trade in value. i think the only other i would go for in that category is the CBR. great bike as well.
