Winnebago sits at the top of Harley-Davidson's neighbor set with a similarity of 0.90 — the strongest pull in a top 10 that spans an unusually wide range of categories, none of them motorcycle brands.
The shape here is broad: scores run from 0.90 down to 0.79 across ten neighbors, with no sharp drop-off that would suggest a single defining cluster. Similarity here measures audience composition — how much two entities' audiences resemble each other in structure — not thematic overlap. What the top 10 reveals is that Harley-Davidson's audience shape is shared most tightly with home goods retailers, health services, and convenience fuel, not with other powersports or automotive brands. Flooring America (0.87) and Carpet One Floor & Home (0.85) rank second and third — both Home Goods and Furnishings retailers. Health & Medical Services (0.83) and Miracle-Ear (0.81) represent Health and Medical Services. Cumberland Farms (0.82), a gas station chain, and Quick Lane (0.81), an automotive maintenance service, round out the mid-tier. The only neighbor sharing Harley-Davidson's own Motorcycles subcategory is the generic Motorcycles entity at 0.83 — fifth overall. Applebee's (0.80) and Albertson's Pharmacy (0.79) close out the ten, adding casual dining and pharmacy retail to the mix.
The cross-kind character of this neighbor set — home improvement, health services, gas stations, and casual dining clustering around a motorcycle brand — points to an audience defined less by vehicle enthusiasm than by a broader lifestyle and regional profile that these otherwise unrelated entities happen to share.
