I just got a mildly used 2005 KX250 2-Banger and I've always riden a 250 4-Stoke so I guess i've never payed to close attention. Am I able to stay in the 250 Class or will I need to move up and race against the 450 4-Strokes? I've been a casual MX rider for many years and i've wanted to get more into it so I got this bike. I'm just going to have a heart attack if i'm going to have to race against all the 450s...

 

Get ready for your heart attack. You could maybe sign up for the old mans class if available in your area. lol Congrats on the ride.
