Older machines have a 4/156mm front wheel with a 4/4in bolt pattern on the rear wheels. Bolt pattern is the same on the Ranger and Razor models, but the 900 and 1000 CC machines have a larger diameter wheel stud. You also have to pay attention to the lug nuts. Wheels with the hub and wheel center tight will have a flat washer nut. Otherwise they will have a tapered lug nut.
Offset and backspace will be different between machines too. Most of the ATVs have a 5-2 or 6-1 but my 850 has a Razor offset with the wheel center at the outside of the wheel. The 1000s are the same. The Razors and Rangers are different also.
It can work, but you just have to pay attention to what you are getting.
