I'm new to TT. A friend gave me the link to this forum... I'm a 37 yr old who raced C and B class, 10 yrs ago (CR250). While I have remained an avid motorcycle enthusiast and rider, I have not been in the dirt for some time. My son has a KX80 and I want a bike to ride with him on weekends. I have ridden a couple of 250Fs and an 05 YZF450, and I love the 4 strokes! I wish I had one back in the day! I've read through this forum extensively, and there seems to be alot of great advice and refference material. I have not seen this 426 yet, but a friend of mine has it and is said to have little time on it. He is the second owner and does not ride it. I'm pretty sure I could pick this bike up for around 2K. I'm in excellent phys shape and very competitive. Is this a good bike for me, or should I find a 450F around the same price range? My riding pref is MX, but will also do quite a bit of trail riding with the family. My son wants to try a bit of weekend racing at the local MX track (Hidden Valley MX, Tn) and I'm sure I'll want to get back into the C class or +35... Concerns?? Thanks for the advice.
