Price and Iranian availability

Base U.S. model-year 2026 MSRP observed on 17 October 2026. Amount is in U.S. dollars and excludes taxes, registration, freight, dealer charges and options.

2025 family reference

The archived 2025 manufacturer page lists a base MSRP of USD 22,599. This is a 2025 reference, not the price of the 2026 model. The specification table describes 2026; a model-year or paint change alone has not generated a duplicate record.

2025 Fat Boy Gray Ghost edition

The official 2025 list shows the Gray Ghost edition at a base MSRP of USD 25,399. This archived edition price is separate from the 2026 Fat Boy described and pictured on this page.

About this model

Fat Boy is identified by its broad Lakester wheels and 240 mm rear tyre. Their distinctive stance also affects low-speed steering feel, making an ergonomic assessment useful. The 2025 Gray Ghost is documented as an edition of this family in the pricing section. U.S. model-year 2026 specifications list the Milwaukee-Eight 117 Custom, 77 kW and 170.8 Nm. A six-speed transmission, 18.9-litre tank and 314.8 kg running weight provide further comparison points. Both ends use disc brakes; suspension details are listed in the specification table.

Specifications are for the U.S. market; Middle Eastern output figures may differ.
Displacement retains the original cubic-inch value; a rounded cubic-inch figure has not been converted into a falsely precise cc value.
Availability of this exact trim in Iran has not been confirmed.
