Vehicle Information
Honda CRF50F Dirt Bike (2004-2026)
The Honda CRF50F, an iconic entry-level off-road motorcycle, has been a consistent choice for young riders from 2004 through the projected 2026 model year. This model is powered by a reliable 49cc (often called 50cc) air-cooled, single-cylinder, four-stroke engine with a SOHC design and two valves per cylinder. Its bore and stroke are 39.0mm x 41.4mm, with a 10.0:1 compression ratio, delivering smooth, easy-to-use power around 3 horsepower, fed by an 11mm or 13mm piston-valve carburetor. The CRF50F has consistently been offered as a single model, without distinct trims, primarily identified by its model year and classic Honda red color. Throughout its long production run, the CRF50F has remained largely unchanged, a testament to its robust and reliable design. Key components like the engine, three-speed semi-automatic transmission, and steel frame have been consistent. Minor updates have focused on aesthetics, such as new graphics and colors, and slight adjustments for emissions compliance. Around 2008, the fuel tank capacity saw a minor reduction from 3.0 liters to 2.6 liters due to a new tank design, and engine tuning was optimized in 2007-2008 for slightly increased torque. However, the core engine displacement and overall design have endured. Q: How can I confirm this product fits my specific Honda CRF50F?
A: To ensure perfect compatibility, please use the year and edition selector at the top of this page.
