Vehicle Information
Honda CR250M Elsinore Dirt Bike (1973-1976)
The Honda CR250M Elsinore, a groundbreaking motocross motorcycle, was produced from 1973 to 1976. This iconic model, powered by a 248cc two-stroke, single-cylinder engine, marked Honda's entry into competitive motocross. Initially launched in 1973 with a lightweight design featuring an aluminum fuel tank and magnesium engine cases, it underwent significant evolution during its short production run. In 1975, the CR250M1 introduced major updates, including repositioned rear shocks for increased travel, a new "up pipe" exhaust system, and a redesigned frame. Aesthetics also evolved with red accents and white fenders. The 1976 model, the CR250M'76, continued this trend with all-red bodywork and frame, though technical improvements were more modest. These changes led to horsepower variations, with the 1975 model reportedly having slightly less power and the 1976 model showing around 23 hp, compared to the 28-30 hp of earlier years. FAQ:
