My gpa has a 1976 Honda cb125s he wants to get running again. We are having issue with tires. He wants Michelin city pro put on. We have found front ire size but no rear. The rear is supposed To be 3.00-17. We can find 80/90-17, would this work? Is it the same size, smaller, bigger? We truly cannot figure it out, any help would be appreciated.

 

Welcome to the forum. Yes that will work. New generation tires called by odd numbers and letters. No longer simple numbers.
