I'm a new BMW owner and a new rider (haven't ridden in 30 years) and LOVE my 2005 R1150GS Adv. I will say it was a bit bigger bike then I was planning to buy but it kinda fell into my lap. I also didn't have a BMW in mind when I was looking. I'm so happy the bike found me. The goal is to be a Moto official for bicycle racing and the GSA really fits the bill. Also helped that it is Farkled out for that purpose.
Right now just trying to put miles in the saddle riding with some very experienced ridders. Taking the MSF class at the end of month.
