The FC 450 continues to be the flagship machine in the Husqvarna Motorcycles motocross line-up. Its class-leading performance is retained for 2025 thanks to a new chromium molybdenum frame that is lighter, perfectly balanced, and improves agility without sacrificing straight-line stability. Further upgrades include new, race-tested Dunlop Geomax MX34 tires and ergonomic bodywork that features new, Swedish-inspired graphics that are applied using in-mold technology for a long-lasting, striking finish.
