That's another choice. I run the E3's on my wifes Road King. Great tire! Of course when I talked to the Dunlop folks, they said the E3 was not rated for the R3's. Go figure! It works just fine on 910 pound Harley touring bike with a passenger and loaded saddle bags! Why would it not work on our 869 pound bikes? I understand the torque question, but I'm not sure how relevant that argument really is. Most of us don't accelerate away from a stop wide open with the tire spinning all the time anyway.
