The tire procrastination on the R90S ended with a coupon code deal from Bike Bandit. Metzelers were hard to find, and not cheap. given the more touring nature of my setup, I opted for some Dunlops with a vintage-looking tread. I must say that they look a little odd on the bike after the very sporty-looking metzelers, perhaps because they were practically bald ! In any case, a quick trip to the local shop for mounting/balancing, and they were back on the bike with greased axles. I took the bike out for a few hours to get the slippy mold off the rubber (at least the middle parts). The tires ride well and once the whiskers are gone they will begin to look ok as well….
