The Dunlop Geomax MX54 front motocross tire is designed for intermediate-to-hard terrain and changing track conditions. This 80/100-21 51M Bias TT tire builds on the proven MX34 and MX53 platforms to deliver predictable handling, dependable traction, and consistent rider feedback from practice through race finish. The Dunlop Geomax MX54 is a tube-type front tire intended for motocross motorcycles requiring this fitment.
Its revised tread design increases the land ratio for improved performance on hard-packed surfaces while maintaining grip in intermediate terrain. Multiple Black Distribution (MBD) technology enhances ground-contact feel and predictability under load, while Progressive Cornering Block Technology (PCBT Advanced) improves cornering grip, slide control, and traction as track conditions evolve. A continuous center groove supports stable braking performance and predictable front-end handling.
The Geomax MX54 also features Dunlop’s race-focused construction for a balanced combination of traction, cornering control, durability, and confidence. The approximately 5% taller rear block specification applies to rear tire sizes and is not a feature of this front tire. High-Resilience Rubber Compound is available only in select 110/90-19, 120/80-19, and 120/90-19 sizes. Confirm motorcycle manufacturer specifications and wheel fitment before installation.
