First look: New Dunlop EN91 Enduro tyre

Dunlop announce latest generation of enduro tyre, the Geomax Enduro EN91 for leisure riders to world championship level.


Built on the knowledge gained at world championship competition, including Colton Haaker’s SuperEnduro World Championship and the FMF KTM Factory Racing riders Kailub Russell and Taylor Robert competing the different North America championships, Dunlop’s new EN91 is designed to deliver versatile performance for a wide range of abilities and riding terrain.

Versatility from a tyre is critical for enduro, as we know, and the new Geomax EN91 brings together Dunlop’s huge experience into a package which they say “offers the highest levels of performance and durability, whether for long-distance leisure rides or professional level competition.” 

“Innovative tread design, new compound and construction”

Replacing the well-proven Dunlop Geomax Enduro D909, the EN91 features a new tread pattern designed to improve traction in sand and mud. The front tyre features a new “ingenius” shoulder pattern to improve handling and reduce rider fatigue. ‘Hex Shape Blocks’ on the front tyre also means more grip is generated at varying lean angles.

“Tilt Crown Block” technology was developed for the new EN91 rear tyre to help provide higher grip on hard terrain, such as rocks. Dunlop says the tilted blocks “improve terrain bite, aid directional stability and increase traction by forcing rocks and dirt to gather around the centre of the crown blocks.”

Durability is important of course and Dunlop claims the new compound has increased shearing resistance but does not compromise performance. By using a high-performance compound, Dunlop has also been able to “significantly improve the rebound properties of the tyre.”

That basically means it helps maximise grip on rocky terrain with Dunlop’s Casing Tension Control System, incorporated into the construction design, to improve compliance on bumps and improves the feedback to the rider.

Importantly the new Dunlop enduro tyres are road-legal so suitable for FIM competition and trail riding.

Luca Davide Andreoni, Marketing Manager, Dunlop Europe explains: “We’ve already had feedback from top riders and teams that the EN91 gives them enhanced performance over a very wide range of terrain. It proves that our objective of widening the versatility of the tyre has been achieved. From soft mud to hard rocks, EN91 has the ground covered.”

The Dunlop Geomax Enduro EN91 complements the Geomax Enduro Soft D907F which is designed for the softest conditions such as sand and wet mud. Available in 90/90-21 Front and 120/90-18 or 140/80-18 rear, the EN91 goes on sale through October.
