The dirt bike depending on what year you want will range anywhere from 6,400- 7,200 (Preferably go with the newest year out such as the new 2010's the Honda CRF250 is great, the new 2010 KX 250f is just as good if not better.) Plus tax, licensing etc will probably be about another 600. The gear incluing jersey,pants and gloves are anywhere from 100-300 depending on brand and design. The boots range from 80-500. Gaerne sg12's are the hottest on the market and the best bang for your buck they have great ankle protection but the best range of movement. The google go for 20-60. Spy's and Scott are the best, foam stays in tact, lenses last quite a while. Helmets range from 100-500. Fox and Shoei make some of the best. I suggest getting a leatt brace which range from 200-600 (the moto gpx sport is the best) Knee Braces are a must you never know how important they are until you end up with messed up knee's. This is a very expensive sport but, the most rewarding. If you want more information on after market parts email me and I'll help you out the best I can.
