I have the Gen 11, I love it,only consider changing it because it gets old,,i like to keep up with age, a 10 year old bike is old,,a bit different with that gen 1 , it's had the forks changed.
I certainly would consider the same,,a 2012 or so to follow mine,,,as all bikes I think you have to sort them to fit yourself,i have and my gen11 is fab to ride.
Butttttt......if you love the gen 1, then the writing is on the table
