i was looking at my buddy's z and it looked like it would fit but it looked like it would be more work than it would be worth. i think to get the motor and the swingarm to line up would be difficult with the frame the way it is. do you have a z and a crf450 motor sittin around or wat, i dont think it would be worth messin around with or least worth puttin the money into. to me the z is a very uncompfterable quad, thats me tho. good luck with it if you fallow threw with it, make sure to post pics
