You can't argue that the 600 is more sporty. It even looks more sporty. The GT's strength is in it's utility. While the 600 is a fun scooter the GT is useful. I can carry a big load of groceries in my GT especially with the BMW top box on it. I think BMW is making a mistake not selling the 600 here without giving it a chance to build a larger following. Neither bike is being very well marketed by BMW, several people told me upon seeing my GT that they didn't know BMW made scooters. Honda used a lot of advertising on their small bikes when they came into the U.S., remember, "You meet the nicest people on a Honda?" That changed a lot of people's out look on motorcycles that Honda quickly became a leader. What do you see about BMW bikes on TV, magazine or newspaper advertisements? Basically nowhere. An advertisement campaign that caught peoples interest would make a big difference but BMW doesn't seem to operate that way.
