the 88 zx600 front rim is a little thinner than the 85 (forks on the 85 are also farther apart) I have used an 88, and a 85 rear rim on my 88 zx600.

 

Thanks. That's helpful too since I'm running an 88 rear wheel and an 85 swingarm. I was wondering though if anyone knew of any other wheels that would fit? I'd like to change the style of the rim.
