Whether the Michelin Pilot SX Racing Line fits your bike is decided by one number: the bead seat diameter, the second half of an ETRTO size. This tire is made for 451 mm and 406 mm rims — 20-inch wheels. If your rim matches, the only remaining question is width, and that is a matter of frame and fork clearance rather than of fit.
