Coming from a lucky owner of this excellent bike I can say it is a solid piece of machinery and I have very little complaints. Especially considering my OCD and impatient attitude. I finally got the exhaust changed and could not be happier. I used SE slip on's from 06 (nice and loud) with a ness big sucker and SERT for the ecm mod. Cost me about $600.00 total which is a bargin for a decent setup. I have not found any major quality control issues with the bike other than the small items that were found when the bike was pre delivery inspected. I got the wrong owners manual which has since been corrected, one of the brake lines had a torn nylon cover on it, several small pieces of chrome had small imperfections, and the front fairing was found to have a small bubble in the paint where the windshield screw is (all being replaced by the dealer). Overall, the engine is strong and quiet, the transmission is unbelievable and smooth, the paint is georgeous in person, and I love all the extras. The only drawback is the attention this bike attracts, you just need to watch people who love to touch and get too close when it is parked.
