I just raced my freinds 1995 cr500. It has a fresh top end with wesico parts. My 2000 xr650r is uncorked, plated. In a drag race on pavement, the 650 was equal until 50mph and then the 650 said good by. On the dirt I smoked him everywhere. The xr shined in the 50mph to top speed range. Riders where equal, we have rode since we were born. Also the rear tires were new or like new. I can say the 500 feals much faster, but is not. The 500 can not match the tourqe and power curve of a 650. The 650's have power everywhere. BRP's Rule. I am going to try to put a picture of my bike in my profile.
