The '99 Yz 125 is my little motocross
toy. I love dirt riding and can't wait to get a road bike. It's a blue
bike and was my first dirt bike ever. It's ridiculously powerful
and was more than I needed to start with. I've gotten used to it and it's quite a rush
to ride. I find there's nothing, for me, like the feeling
you get from dirt riding. You go anywhere
you want and as fast
as you want. No limits
are placed on you except for those you choose to place on yourself.
