Like others have said, don't worry about other riders. Work on improving yourself. Some of the guys that have become pretty quick started out focusing and working on their riding without concern for what others were doing. This really is the case. What may make you quick your first few track days, will actually slow you down once your skill improves.
An SV650 is a SENSATIONAL bike to start on, and it is just a great bike for the money for anyone.
And look up Judy (HondaGalToo), she is a cool chick with a lot of experience. Now that just sounds bad....or good, depending on your perspective. Well, I mean that she has been riding a long time and has ridden a lot of different kinds....ok, this isn't getting any better.
