The Dunlop Geomax MX54 rear motocross tire is designed for intermediate-to-hard terrain and delivers consistent, predictable performance as track conditions change. This 120/90-18 tire features a 65M speed and load rating, bias construction, and tube-type fitment for compatible motocross motorcycles. Built on the proven Geomax MX34 and MX53 platform, the MX54 provides balanced traction, cornering grip, durability, and rider control throughout a race.
Designed for riders who need dependable performance as tracks dry and become more hard packed, the Dunlop Geomax MX54 uses a revised tread pattern to increase land ratio and improve hard-terrain capability while preserving grip in intermediate conditions. Multiple Black Distribution (MBD) technology enhances ground contact feel and predictability under load, while Progressive Cornering Block Technology (PCBT Advanced) supports cornering traction and slider control on firmer surfaces. The approximately 5% taller rear block height further contributes to traction and durability in demanding conditions.
The Dunlop Geomax MX54 rear tire is a direct replacement option for compatible motocross applications requiring a 120/90-18 bias, tube-type rear tire. Verify motorcycle manufacturer specifications, wheel size, clearance, and tube requirements before installation. The manufacturer part number and vendor part number are both 45278513.
