The Dunlop Geomax EN91 EX rear tire is designed specifically for Hard Enduro racing and demanding off-road riding. This 140/80-18 tire uses a super-soft rubber compound to deliver strong traction across rocky, technical, and low-grip terrain. Its bias construction and tube-type design provide the performance characteristics required by serious off-road riders.
The EN91 EX features an additional construction ply that improves the linearity of sidewall stiffness while enhancing damping and absorption performance. Progressive Cornering Block Technology (PCBT) increases the surface area of the interior shoulder blocks, while strategically designed tread angles improve grip, stability, and slide control during aggressive cornering.
This Dunlop Geomax EN91 EX is supplied in the 140/80-18 70R size and is intended for compatible off-road motorcycles using an 18-inch rear wheel and tube-type tire setup. It is not DOT approved and is not FIM approved, making it intended for closed-course competition and off-road use rather than public-road operation. The manufacturer part number and vendor part number are both 45272501.
