Vehicle Information
Honda CRF300L Motorcycle - Dual-Sport (2021-2025)
The Honda CRF300L, a versatile dual-sport motorcycle, was available from 2021 to 2025. It is powered by a reliable 286cc liquid-cooled, single-cylinder engine, delivering approximately 27 horsepower. This model succeeded the CRF250L in 2021, bringing increased displacement, power, and a lighter chassis. While the core engine remained consistent across these years, Honda introduced significant updates. In 2023, the CRF300LS (Low Seat) trim was launched, offering a more accessible seat height. Further enhancements arrived in 2025 for all CRF300L models (Standard, LS, and Rally), including updated suspension damping, an improved cooling system, standard LED lighting, new graphics, and standard ABS (previously optional on the Standard and Rally trims).
