No acquaintance with seller, just a find

I ride an ST3. It is a damn rocket, you feel fine doing 100, the bike handles so well it's like you're in a parking lot when you're on the freeway. Things do happen quickly at that speed, be careful. If you get the ST3, get ABS! I love the smoothness of the ST3 engine. The bar position does bother ...

It's a toss up, the 1000 has enough power to not need to be thrashed to keep up with traffic, the 620 is new. Remember, though you take a real beating on price when you buy new. All other factors being equal, I would go used.
