Just finished my motorcycle safety course this afternoon and I spent the weekend riding an '09 Ninja 250. Hopped on my 500 as soon as I got home just to feel the differences, and boy are there differences. Brakes are the biggest one, I can't believe what a difference. The Ninja's brake were so touchy(but really effective once you got used to them), nothing at all like mine. Other than that, I like everything about my bike better. More class, more style, not to mention the soul a 36 year old bike has.
Didn't really think I would enjoy riding a crotch rocket too much, but I have to say it wasn't bad at all. Still wouldn't trade it for my bike though.
Perfect score on the road test, I now have my M2. All in all, a good weekend!
