Dunlop Geomax AT81 EX Rear Motorcycle Tire 110/100-18 64M Endurocross Gummy Compound Off-Road

OVERVIEW

Designed specifically for the rear position, the Dunlop Geomax AT81 EX is an endurocross motorcycle tire engineered for aggressive traction, load support, and precision handling on technical terrain. Its specialized gummy rubber compound delivers consistent grip across hard-packed dirt, rocks, and loose substrates, while the blackwall finish provides durability aligned with traditional off-road applications. Built with a 4-ply reinforced carcass and dual nylon layers, this tube-type tire stabilizes heavy off-road machines during demanding competition and trail riding.

ENGINEERING & PERFORMANCE

The Geomax AT81 EX utilizes a dedicated gummy rubber formulation that retains pliability to maximize surface bite and resist heat degradation during prolonged throttle inputs. A four-ply reinforced carcass reinforced with dual nylon layers locks down sidewall deflection, managing the structural strain of heavy enduro bikes hitting bumps and ruts. Flexible block deformation and plush pad recess engineering allow the tread to compress around obstacles, improving impact absorption and maintaining ground contact. Lateral shoulder grooves multiply biting edges during aggressive lean angles, while the linear center-block arrangement extends the footprint for reliable forward drive traction.

WHY RIDERS CHOOSE THIS

Riders reach for the Geomax AT81 EX when facing steep climbs, rock gardens, and loose berms where consistent forward grip dictates race pace. The compliant carcass geometry and stretch-resistant gummy compound deliver immediate mechanical authority without sacrificing steering feedback during rapid direction changes. Tube-type setup paired with reinforced nylon sidewalls simplifies installation on traditional spoked rims while minimizing rider fatigue over extended enduro runs. This precise balance of flexible tread engagement and structural rigidity keeps the motorcycle tracking predictably exactly through the sections that demand it most.
