Yes it is 2005 model but i got it in 2006, i got 2 take one of 2005 or 2006 but for the look 2005 is much better, speed is the same i guess.... i stopped riding it since my 8th week out of the show started
i dont want to have any accedent at this time... after the shows i have no problems 
Yes...same motor but they are using a different clutch in 06, added a steering dampener, & undertail exhaust tip.
The steering dampener is much needed. When ever you pull the wheel or stomp it hard....you can tell a difference. Also...when going above 130mph....there's less vibration.
Honestly, if the deal was good on the 05' I would go ahead & just add my own.
