i know this guy who has a 2004 crf 50 and he wants to trade me for my SDG. Im all for it, but i dont know how much extra to charge him. his 50 has a bar hit, exhaust, i-shock, and stiffer fork springsand it has a lot of hours on it. I was thinking Around $500 extra, Because my SDG only has maybe 15 hours on it, its basically brand new.
