I just installed a front 90/90 21. It replaced a Scorpion Trail MT. The Pirelli was a knobby looking tire, not the more street looking one. It was an excellent tire. I'm not sure if they still make it. Anyway my first thought after the Annakee was mounted was, "That's a really skinny tire." It's the proper size, but I've never looked at any of the other tires I've had mounted and thought it was super skinny. The Anakee looks skinny.
I just got back from a little 130 mile jaunt and noticed no increase in noise over the Scorp. I didn't notice any tire noise at all. Don't know what's going on with the folks that hear loud noises from the Anakee 3.
