The 610 is great fun Bike with lots of power. I found the stock rear suspension stiff and had it and the front re & re-ed. It is as close as you are going to get to a perfect Dual-Sport bike. The front wheel comes up with just a turn of throttle. It's fine on the "B" stuff.
But, you have to ride them both and decide.
I don't know what a 610 goes for, but just do search.
