Not many racers here on .org.
It's cool. There's not many of us out there still " " (*crazy enough, *in shape enough, *dumb enough, *stubborn enough, *determined enough, fill in your own blank) to be racing these machines still.
But ya know, racing a 450 I'm just another guy on a quad, nothing special about it. Win or lose, when I race my 250r, I get special attention. People may have saw me lose, but then they come over and say "man, that things sounds wicked" or " that's a sweet ride you got". What do they say to the 450 riders, "hey, look, you got the same quad as everybody else!"
