Harley-Davidson make a couple of these transmission and oil line cover which they call a "Transmission Interface Cover." Comparing the Kuryakyn cover to the H-D Covers is no comparison. The die-cast metal is thicker with Kuryakyn. Style of the Kuryakyn Cover is superior to either version that is offered by Harley-Davidson. Cost-wise, they are comparably priced. I have the Kuryakyn Transmission Cover on my '03 FLHR and have gotten great comments from other bagger folks. H-D left a huge blank space in manufacturing of the Twin Cam Touring Engines. This Kuryakyn Transmission / Oil Line Cover is THE way to smooth it out with CHROME!
