I also went for the deal. I bought from motorcycle-superstore.com. $125 shipped. Not the "E" model. Until this thread, I wasn't aware of one, and neither Pirelli's or superstore's website listed one. I saw that mototire did. Oh well, maybe next change.
Let's post results please. How long to get your tire, how much for mount, balance, how much mileage. I'm curious about the differnece between the "E" model and standard as to wear and performance. Every review I've read about this tire is positive. As to buying in town, I'd like to, but my local dealer wanted $210 including tax to CARRY the tire out the door. The REAR tire only. I didn't even price the front. Mount and balance extra. $125 shipped for the rear plus $25 for the front is just to good a deal to pass up.
