I'm 41 and excited to get back riding again. I just bought a 2000 XR400 after a lot of thought,paid $2250. for it. I rode last week at a friends indoor Motocross track and had a blast. I rode three different bikes and have had a really tough time deciding what to buy...whether I should get a MX or a trail bike. I have been reading this forum almost everyday and from all the great posts I have read I made my decision and bought the XR. I don't think I can really go wrong with it for the money and it will get me back trail riding again. I quit racing MX in 1984 but I did continue trail riding until 1990. I don't know if I'm going through some "middle age krazy" stuff or not but I know every spring I go through this wanting to ride again thing. Thanks for all the great input on this site, I hope to contribute some myself in the future.
