Oh yeah..and another thing..
When I bought my 13 I looked at several 11's. I decided on the 13 because I was "done" with carb'ed bikes. I never thought I really needed some of the bells and whistles standard on the 13. But....
I found that the electrically adjustable windshield is the greatest thing since canned beer. Really. Who'dathunkit ? It's now an item I'll never be without, and I'm an anti-farkle kinda guy. It's that good.
SO......I gotta recommend that you do whatever it takes to find a 13 over an 11. It really IS a generation ahead. Absolutely no regrets spending the extra dosh for the 13, and as bike-buyers go I'm as cheap as they come.
Just food for thought.
