Hey guys, just like the title says 2003 crf450 motor Athena Big bore, stroker crank, ported, 14:1 compression, very little time on this motor less than 10hrs since new. I guarantee you will be very impressed with the power this motor has. I'm only selling it because I have another one that is not quite as radical that I run and this one is a little excessive for mx and xc. $1800
