It's a difficult position to be in...I'm not sure about the validity of the "deal" you'll be getting on the bigger bike, but I'll assume it's a good one. I've always found the purchasing of motorcycles to be somewhat odd, in my opinion at least. I've known folks who buy a bike, say it's the best they've ever been on, and then two years later, sell it for something different. While I understand the need/want to try something new, I'm curious as to the regrets one might have later on after he or she has sold a bike. For some reason, when I think about selling the "Purple Nurple" ('01 violet and gray color scheme, this is the name my friends have given my bike; I hated it at first, but I've adopted it for some reason), I always think that if I ever did, I'd regret it and think "What could have been?" Somewhat similar to what someone else said about the girlfriend, same sex, different woman, different positions or something like that, is that really a good thing?? I don't know, but for some reason I see myself in 5 years with a liter bike and always missing the old Purple Nurple. Maybe that's because it was my first bike (and only one so far). I guess I just have trouble letting go of things...
Any old EX owners, or owners of more than one bike over time have any good advice or insight??
Good luck with your decision!
