The Dunlop Geomax Factory Spec front tire is engineered for off-road motorcycles competing in soft to mixed terrain. This 80/100-21 tire uses a proprietary ultra-high molecular mass compound with extended polymer chains that increase bonding points with carbon molecules. The result is a strong, durable rubber compound that helps the tread knobs penetrate the ground for dependable traction and confident handling.
The Factory Spec model features an advanced apex designed to improve responsiveness and provide additional support during higher-speed riding and harsher landings. Its single-radius profile delivers predictable control characteristics as track conditions become rougher, helping riders maintain stability and steering precision throughout changing terrain. The tread design also helps reduce knob deformation, supporting consistent performance during demanding off-road use.
Designed for motocross and other off-road motorcycle applications, this Dunlop tire performs in soft terrain, including loamy soil, sand, and muddy conditions, while remaining effective in a mixture of packed and loose soil. The front fitment is intended for motorcycles using an 80/100-21 tire size, with a 51M load and speed designation. Manufacturer part number and vendor part number: 45276500.
