Harley-Davidson River Rock Grey-951453 (E77) Touch Up Paint

The Look

Introduced as a standout for the 2020 lineup, this color defined a new industrial era for Harley-Davidson. You typically see it hugging the aggressive lines of the Road Glide Special or adding a rugged, earthy weight to the Fat Boy. It is a complex, moody shade that plays tricks with the light. In the deep shade of your garage, it looks nearly black or dark charcoal, but once you pull out into the sun, the metallic depth wakes up, revealing a warm, stone-like undertone. It was designed to look tough and weather-beaten right off the showroom floor, making it a favorite for riders who prefer a mechanical, non-nonsense aesthetic over high-polished chrome.

Technical Details

This finish is a metallic, which means it relies on tiny flakes to create that signature depth. Because it is often paired with a "Denim" or matte topcoat, you have to be careful during application. Metallic paints are prone to mottling, where the flakes cluster together and create dark streaks or spots if the paint is applied too heavily in one go. If your bike has the matte version, do not try to buff or polish the repair area afterward, or you will end up with a shiny spot that ruins the factory look. Before you spray or dab Harley-Davidson River Rock Grey-951453 (check for code E77), you need to shake the container for at least a full minute to ensure those heavy metallic particles are suspended evenly in the liquid.

Best Practices

Harley-Davidson does not always make it easy to find a physical label, so if you are searching the frame, check the steering head or the down tube near the neck. Most riders find it easiest to verify the code through their owner's manual or by providing a VIN to a local dealer. When you are ready to start, test the color on the included card first to get a feel for the flow and the pigment density. Whether you are using a brush or an aerosol, keep the container moving to prevent the paint from pooling. If you are filling a deeper scratch, apply several thin layers rather than one thick one. This allows the metallic flakes to lay flat and gives you a much better match. Give the area plenty of drying time between layers to ensure the finish sets hard and stays true to that 2020 factory sheen.
