i am in the market to buy a new enduro bike for myself. i live in costa rica, but would like to buy the bike (honda crf450r or x) from you and have the complete conversion performed by you. what would be the cost to do so? what model do you recommend. i have been riding street bikes for years (bmw k1200r modified to 180hp) and i am selling my f650gs dakar to switch into a new bike. i am new to motocross and would love your recommendation on size. should i go with a 250 or 450? i am 5'10" and 185lbs. i like the idea of a 250 for its light weight and quick response handling, but am affraid i will out grow it quick and regret not going for the 450. what do you recommend. do i buy the bike from you or buy the bike from a local dealer and then bring it to you?
