I just bought a 2001 600 with a Power commander, can and headers. And I thought that a 600 might be a little weak for my first bike, but I'm glad I got it, and didn't get something bigger. It's got plenty of power. Thought i'd try my hand at a street bike and was sick of waiting for my buddy to buy one for the past 4 years, heh. So i'm kinda garaging the vet except during the day, cause it's too hot too ride here during the day. (AZ).
