I have another, related question.
If you still love your one and only bike, and would definitely buy it again; Is one bike enough?
I wouldn't trade my R12GS for anything, but got me a serious hankerin' for a new Monster 1100 Evo.
Honestly, I've owned quite a few bikes over the years, and loved all of them. Even the '65 BSA that took all my money in my teen years and rarely ran for more than a few miles at a time.
If you could keep your current bike, is there a bike that you've ridden that would also get a good amount of saddle time if it was also in your garage? What is it?
