Hi everyone I picked up a 2006 KX250F this last Tuesday, rode it today at our local mx track, what a great bike! I was faster and felt allot more in control on the KX compaired to my 2002 RM250. I also got a few laps on my friends 2006 KX450F another fantastic bike, I was able to go fast on the 450 but I got arm pump quickly. I wish I could have them both but I am very happy with the 250. I will be changing the oil and checking the valves this week and posting the results on the appropriate thread. Ride, have fun, change oil.
