I have the Thailand Michelin's on my R18C with almost 11,000 miles and am pleased with the wear.Probably get over 20,000 easily if not 25,000.Of course I am a nut keeping a eye on the air pressure.I have been running the Michelins on my other bikes but purchased a set of the new Crustec Metzlers and find them to be equal in performance and wear.
If you have a 19 inch wheel and want your front tire to have the same width as the 130x90-16 that is on the R18C, the 130x60-19 will have add some stability/grip with a little slower steering.
