I found your comparison interesting. Good to see a owner have actual guy on the ground intel from these two bikes. I have not ridden either bike, but would think the GSA would be better off road. I figured the P. Boxer would have a lower center of gravity. What type of terrian do you ride? I'd only go forest road and well packed single trail. Does the ABS, (not be able to turn off, right?) do well off road? Most reviews read that it is not a negative off road. As long as you do not go down a steep grade with a lot of speed, a rider should be fine right? If I had to pick between the two bikes, as a noob and a very frugal person, I'd go with the economical choice for an Adventure touring ride. The price to repair stuff is cheaper, and the locations to get repair is more frequent. I also like how the S10 can have the seat lowered down, I'm just 5'-10" and I found the GSA hard to lift up from the kick stand. :eek1 But, I really like the GSA. She has been around for a while and also has great value.
