The Dunlop Geomax MX54 rear motocross tire is designed for intermediate terrain with expanded performance on hard-packed tracks. This 120/80-19 tire features a 63M load and speed rating and bias tube-type construction, making it a suitable replacement for compatible motocross motorcycles. Manufactured by Dunlop and supplied under vendor part number 45278516, the MX54 builds on the proven Geomax MX34 and MX53 platform to provide consistent traction, predictable handling, and dependable durability as track conditions change.
The Dunlop Geomax MX54 uses an updated tread design to increase land ratio for improved grip on dry, hard-packed surfaces while preserving traction in intermediate terrain. Multiple Black Distribution (MBD) technology improves ground-contact feel and predictability under load, while Progressive Cornering Block Technology (PCBT Advanced) supports cornering grip, slide control, and acceleration traction. The approximately 5% taller rear block height is engineered to improve forward drive and wear resistance during demanding race conditions.
Designed for motocross riders who need balanced performance from practice through the final lap, this rear tire delivers a combination of traction, cornering control, braking stability, and service durability. Fitment depends on the motorcycle model, wheel size, clearance, and tube requirements, so verify that your motorcycle accepts a 120/80-19 rear bias tube-type tire before installation. Use with a properly sized inner tube and follow the motorcycle and tire manufacturer’s mounting, inflation, and operating recommendations.
