I am going to replace the rear tire on my bike and was planning on putting on Dunlop 401 Harley Davidson series. I called cycle gear and they had a D404 in stock in my size. The two tires look the same except the 404 doesn't say Harley on it. Are these both the same tires? Anybody know anything about the 404's? I can live without having the harley logo on the tires and am much more concerned with quality.
