Hi, I'm new to the forum and I had a question: I'm taking a motorcycle course soon and although I've ridden on the back of one many times I've never actually rode by myself. I'm 5'10" and 140lbs and I was wondering if the GSXR600's are too much for me to handle? I have no problems with the weight or touching the ground, but I'm told that its a huge risk to start on and (from my dad) I'll get myself killed. If its true, what bike should I be getting? I always thought the 125cc or 250cc would be too small for my size.
