I will say right out that I ride a YZ250. I have owned XR's and CR's in the past though, and all have been bullet proof. But I have to give props to Honda. My father has an 83 CR250 that he has had since 1990. His buddy owned it before then. This bike gets ridden all the time, either hill climbing, trails, or at the track. Lately it has been ridden 3-4 times a week by my brother who borrowed it to ride with his kids. Well last week I asked my father if he has ever put a new top end in it. Nope! And his buddy that owned it before him never put one in it either. This bike still screams, although the power is all low to mid, with absolutely no top end. Congratulations to Honda for making such fine bikes. I believe it is bikes like this that gave Honda its reputation. This bike shows no sign of dying, and will hopefully keep running long into the future.
