I know here goes another! Well I would like some help. I am 38 and need to get back into shape for racing dirt bikes off road (my first love) and thought this would be better than being bored ass he!! in a gym. My brother gave me a Trek VXR 200, so I have a bike (nit sure how good it will be) what more do I need to know? I don't want to end up trail trash and look like a fool on my way to the hospital. If I enjoy this I plan on getting a new bike but didn't want to drop $1000 bucks on it just yet. Thanks for any help.
