So I'm new to this scene, but DEFINITELY looking to get a dirt bike so that I can change the span of my riding season to YEAR ROUND... I've got a $500 Yamaha gift certificate that came with the purchase of my Yamaha Edition Tacoma, so am in the market for a Yamaha dirt bike. Where exactly do I start out in the market? I'm looking for new, as the GC is only good for 2007 or newer, ummm, rider's specs are 5'4", been riding for 4 years, and I ride an R6 on the street (whether or not that makes a difference I don't know lol). Anywhoo, any info/advice would be greatly appreciated as I have test ridden a few friend's bikes, have no clue what models they were, and no clue where to start... all I know is I've tried it out a few times and I'M HOOKED!
