Vehicle Information
Honda CRF450RL Motorcycle - Dual-Sport (2021-2026)
The Honda CRF450RL, available from 2021 to 2026, is a versatile dual-sport motorcycle designed for both off-road adventures and street legality. It features a robust 449cc liquid-cooled, single-cylinder Unicam engine, known for its reliable performance across various terrains. This model maintains a single trim level throughout its production run for these years, emphasizing its core identity as a race-inspired, street-legal enduro. A significant update occurred in 2021. The model, previously known as the CRF450L, was rebranded as the CRF450RL to highlight its racing heritage. This change brought updated ECU and fuel-injection settings for improved performance, along with standard plastic handguards and a new oval exhaust. From 2022 to 2026, the core engine and chassis specifications have remained largely consistent, with no major generational changes. Q: How do I ensure I select the correct parts for my Honda CRF450RL?
