Thats Max on the 450, great kid and a pleasure to bring along anytime. He'll be 18 in a couple weeks, the bike I am riding is 23 years old.... kinda puts it all in prospective.
I rode that bike a couple weeks ago and it's a rocketship, I couldn't ride it at all because I'm used to a 125 2 stroke and although they both have 2 wheels it pretty much ends there. The best I can explain it is you are riding a small block Chevy, so much fun to drag race it but then you have to stop it and the extra 40 lbs adds up exponentially.
When I came back to the sport it was on a KTM 520 and I progressively reduced the displacement eventually landing on a 125, I couldn't be happier with the outcome....
2 strokes rule!!!!
