i had an 87 kx500 rode it at smith rd a couple of times was'nt much fun there! i bought it for trail riding & hill climbing at which it was great ! just point it at a hill and pull the trigger!!!!!!
I've had 500's mostly my whole life. In fact I'm trying to get rid of my '03 YZ450F and get another. Love them!
Here's my last KX I Had, a '99
My H.O.T. '92 CR500. this was Eric Keho's National bike.
. You guys want to get faster, buy one of these and practice on it, and 450 will seem like a 125.
