Dunlop developed their Geomax MX33 dirt bike tire with the help of top Motocross pros. As a result, the all-new MX33 is the new industry standard for riding a soft-to-intermediate terrain tire on your dirt bike. Dunlop's innovative new technologies incorporated into the Geomax MX33 tire offer superior grip, slide control, bump absorption and enhanced durability. Whether you choose the rear or front Geomax MX33 tire, you get the same superior results. Altered Block-in-a-Block shape on the rear tire increases surface area of the interior block, while additional tread angles enhance grip, stability and slide control. The front (and rear) tire includes new tie bars that connect each knob, improving durability by reducing flex at the base of the knobs. Dunlop's new Advanced Apex Design improves shock absorption by diffusing shock through a taller, thinner apex inside the sidewall.
