hey, you can't beat the sound of a two stroke! that's what I was raised on. my first bike was a KX80 (that I eventually blew up) and a while back I owned a KX500 for a while (that I broke 3 vertebrae riding the first day i owned it). that bike was a legit beast and I honestly regret selling it but I was moving and didn't need so many bikes.
KX is same family as my KMX (bascily the same bike with minor changes), and for those who don't know the beast KX500, here it is:
(It can produce up to 70HP which is crazy high)
