i have a 03 sv650s. started on the naked version sv650 (1999 year). ive been riding for 2 years and iam still not sick of it. dont get a 250cc u will learn the basics of riding and then the 250 is not gonna satisfy anymore. yes, a suzuki gs500 is an awesome beginner bike but you will want more once you learn the basics. i personally think the sv is the best choice or maybe the new kawasaki ninja 650r. the ninja 650r looks super sweet though. especially the black with the red frame choice.
