Used Excelsior-Henderson Super X parts are available at Sun Coast Cycle Sports. The Super X was a heavyweight American cruiser produced briefly from 1999 to 2000 by Excelsior-Henderson Motorcycle Manufacturing Company in Belle Plaine, Minnesota. It was powered by a 1,386cc (84.6 ci) V-twin engine producing approximately 82 hp, with a five-speed transmission and belt final drive. The company aimed to revive the historic Excelsior and Henderson motorcycle brands but declared bankruptcy in 2000 after producing only an estimated 1,900 units. Parts are inspected, individually cataloged, and ship from Florida.
Super X platform and parts compatibility
The Excelsior-Henderson Super X is a unique, standalone platform. The 1,386cc 50-degree V-twin engine was designed specifically for the Super X and shares no components with Harley-Davidson or other American V-twin manufacturers. The chassis, bodywork, and all mechanical components are proprietary. With only approximately 1,900 units produced and no manufacturer support since 2000, OEM parts are extremely rare. Used components from donor bikes are among the few remaining sources for maintaining these collector motorcycles. Some aftermarket brake, suspension, and electrical components from the era may be adaptable.
Common Super X failure points and replacement parts
Parts availability: The single biggest challenge with the Super X is finding replacement components. With no manufacturer and a very small production run, every part is scarce.
Electrical system: The electronic fuel injection and engine management systems were designed in the late 1990s and use proprietary modules. ECU and sensor failures are difficult to address without donor parts.
Fuel system: The EFI system can develop injector and fuel pump issues. OEM replacements require donor sourcing.
Rubber and seal degradation: On machines now 25+ years old, all rubber components (hoses, seals, gaskets, tires) should be inspected and replaced as needed regardless of mileage.

Frequently asked questions
Q: How many Excelsior-Henderson Super X motorcycles were made
Approximately 1,900 units were produced between 1999 and 2000 before the company went bankrupt. This makes the Super X an extremely rare motorcycle. Surviving units are considered collectible, and maintaining them requires sourcing parts from donor machines or fabricating replacements.
Q: Does the Super X share parts with Harley-Davidson
No. Despite being an American V-twin cruiser, the Super X was designed from the ground up with a proprietary engine, chassis, and all components. It shares no parts with Harley-Davidson, Indian, or any other manufacturer.
The Excelsior-Henderson story is one of the most dramatic in American motorcycle history. The company was founded in the late 1990s to revive two historic American motorcycle brands, Excelsior and Henderson, which had ceased production in the early 1930s. With significant venture capital funding, the company built a state-of-the-art factory in Belle Plaine, Minnesota, and designed the Super X entirely from scratch as an American-made heavyweight cruiser to compete with Harley-Davidson. The 1,386cc 50-degree V-twin was a clean-sheet design with electronic fuel injection, five-speed transmission, and belt drive. Despite positive reviews and genuine customer interest, the company could not achieve the production volume needed to sustain operations and filed for bankruptcy in 2000. Surviving Super X motorcycles are now collectible, and their proprietary design means every component is rare.
Q: What is an Excelsior-Henderson Super X worth today
Values vary based on condition and mileage, but clean, low-mileage Super X motorcycles typically command collector premiums due to their rarity (approximately 1,900 produced). The motorcycle's value as a collectible piece of American motorcycle history often exceeds what comparable Harley-Davidson models of the same era sell for. Parts availability is the primary ownership challenge.
