BREAKING: A historic Harley-Davidson motorcycle, the 1908 Strap Tank, just sold for an astounding $935,000 at a Mecum auction in Las Vegas, making it the most expensive motorcycle ever sold at public auction. This sale, which occurred earlier today, marks a significant moment in the world of motorcycle collecting, capturing the attention of enthusiasts and investors alike.
The Strap Tank is one of only 450 motorcycles manufactured in that year, with its rarity contributing to its skyrocketing value. Discovered in a barn in Wisconsin in 1941, this motorcycle remained in the same state for over a century before its restoration and auction debut. The bike, featuring its original four-horsepower engine, showcases Harley-Davidson’s pioneering spirit and historical significance.
This auction is not just about a high price; it represents the enduring legacy of a brand that has captivated the hearts of riders for over a century. Experts highlight that such rare models are not just vehicles; they are pieces of history, often unseen by most enthusiasts.
The 1908 Strap Tank isn’t the only rare model that collectors are clamoring for. The 1934 CAC Speedway Racer, of which only 12 units were produced, also commands high prices at auctions. One example fetched approximately $91,000 at a Bonhams auction in 2025. Despite its limited production, the CAC Speedway Racer symbolizes Harley’s ambitious foray into speedway racing, a sport that saw a decline shortly after its introduction.
Meanwhile, the 1910 Model 6-A introduced a revolutionary magneto ignition system, enabling engine starts without pedaling. Only 334 units were made, and while exact survival numbers are unclear, one restored model was notably listed for between $85,000 and $95,000 at auction in 2020.
Harley-Davidson’s experiments didn’t stop with speedway racing. The MX250, their sole motocross bike, was produced in 1978 with around 1,000 units made. However, it struggled in the market, and reports indicate that only four examples remain intact in Europe today. Even the first unit, Serial 001, only achieved a final bid of $18,500 in 2021.
The Sport model, produced between 1920 and 1923, was a pivotal point for Harley, marking the first time the brand named a model instead of using a letter-number designation. While fewer than 10,000 units were sold, its design reflects Harley’s efforts to penetrate the European market, showcasing their adaptability and historical significance.
With such a compelling array of rare motorcycles, Harley-Davidson continues to hold a special place in the hearts of collectors and enthusiasts. The sale of the Strap Tank today not only sets a new benchmark in auction history but also brings renewed interest in these extraordinary machines.
As collectors and fans reflect on this monumental sale, the motorcycle community eagerly anticipates which rare Harley will make headlines next. Stay tuned for more updates on this developing story.
