I ordered a pair of Michelin T63s for my '02-S and was surprised at how small the 80/90-21 front looks. I understand I ordered the smaller of the two sizes (90/90 was other option), but figured it would be similar to the 3.0-21 Shinko I had (3 x 25.4mm=76mm). In reality, it looks like it will end up being 15mm-ish narrower. I don't really object to giving it a shot. I suspect it will help rotational weight and turn-in, but wonder if it will handle ok on the typical roads and trails in North Central WA. The bike sees a fair amount of hard-packed dirt roads with loose gravel or rocks on top, as well as a smaller amount of trails varying from smooth to loose/dusty to rocky. I figured a narrower tire would be more agile and quicker steering, which is probably right. This tire's extreme narrowness caught me by surprise, however. Like I said, I don't really mind giving it a go. Just wondering if any other DRZ riders choose narrower tires specifically? FWIW, I went with the 120 rear tire in this set.
