HI; I have a good running CR125 I believe the bottom end to be around 96 and the top end is 99. I Rebuilt the bottom end last year with all new bearings seals and Crank. The top end is fresh. No time. I used only for a few practice days Never raced. Can sell the motor complete less Carb Pipe and Fuel Pump, and Radiator. Have a nice Motor mount I could include if you are interested. I would sell for around $1200.00 Thanks Steve in Florida 727 521 6856 or slaymon@tampabay.rr.com
