Seems the detent spring was an issue with the 2008 model , mine went a few months ago , but it was'nt an expensive fix ,, the mechanic said they must of fixed the new spring stronger because the new one is a different part number . The touring has a narrower back wheel to enable the panniers to fit , but reports were it makes the bike handle better , but has with all bikes , i don't take any notice of this one handles better than that one , i feel thats all down to rider ability ,, i've not rode the standard rocket , but i've certainly been left behind by a few of them , and some with the car tyres in the twisties .
Getting that tune done opens the touring up , but then again its got a lot of power anyway .
