Many member's are running these (Dunlop E 3's) with great results. I switched over to these last year and am happy with them. Dennis Kirk had the best prices when I ordered mine If I remember right it was 178.00 for both front and rear shipped to my door in about 3 days.. At times they will have coupons available as well.

I never had a prob running the OEM HD Dunlops...I've been through 3 sets of front and rear in 30K miles..(I change both every 10K to match tread)..most folks can run 20K on the front and 10K on the rear without probs though..I guess I'm picky...
