For 2020 the CRF450L carried on mechanically unchanged, with Honda limiting the update to new graphics. It kept the CRF450R-based Unicam single with fuel injection and electric start, the aluminium twin-spar frame, long-travel Showa suspension and titanium tank, and remained a road-legal trail machine with a focus on off-road ability.
