[B]IM 16 years old and have a cool job at the state park and ive had motorcycles all of my life but havent watched the motorcycle market lately. I wanted a crf250x because price isnt bad but i heard about the valve problems and maintenace is horrible compared to a 2 stroke? Whats going on? I heard that blitz makes valves will solve this, is a crf250x a reasonable choice for a enduro or a wr450? Im 5' 10'' 195lbs? Need some help before i buy soon. what would be a good enduro, i plan on not riding too much street but occasional.
