I had Pirelli MT60 installed on my Versys. When I left the installer I went down as I thought they hadn't cleaned the lube. When I got home, I checked the tire date and they were nearly 5 years old. I contacted Pirelli Thailand who at first seemed quite helpful and willing to change them, but never returned my calls after. Big companies don't give a shyte if they know they can get away with it.
Not only will I not use the dealer again, but I will not use Pirelli either. The stupid thing is, I can be charged for defamation for dissin' them despite being out of date!
