They are okay. I am not terribly fond of them myself. When my former BF would work on somebody's street bike I would go with him to test it. That was fun. Not so fun was when we hiked up a steep hill on our farm and sat on large rocks drinking cinnamon Schnapps. I didn't realize I was toast until I tried to stand up and walk. So my BF went to the house and brought back one of his dirt bikes and we both got on it. What he had not anticipated was how the weight of another rider going down hill would limit his ability to use the brakes. Yikes.

I was scared half to death thinking my head was going to bounce off a tree. When he finally was able to stop I decided I would walk the rest of the way home drunk or not.
I still have one street bike & several dirt bikes in storage. Wanna buy one cheap???
