Dunlop has replaced its Geomax EN91 competition enduro tyre with the new Geomax EN92, adding a second, softer compound built specifically for wet, root-laden and rocky ground. The EN92 is FIM/DOT-approved for competition use and started rolling out across Europe in early 2026, with the fresh press wave landing this week confirming size and spec details for the wider launch.

I’ve destroyed more knobblies on wet Welsh hillsides than I care to admit, and every time a manufacturer says “new compound for rocky terrain” my garage credit card starts vibrating in sympathy. This one at least sounds like it’s aimed at people who actually ride enduro, not just people who own an enduro-styled naked bike and a strong opinion.

Two compounds instead of one

The Geomax EN92 comes in a standard medium compound plus a new EN92 SOFT specification, aimed at wet, root-covered, uneven and rocky sections where the old EN91 line only offered one blend to cover everything. Dunlop’s off-road product lead, Dmitri Talboom, says the tyre “combines several of our most innovative off-road technologies,” borrowing tread ideas from the brand’s motocross range rather than treating enduro as an afterthought.

What actually changed on the tread

The EN92 carries three named technologies: Progressive Cornering Block Technology (PCBT) for more predictable grip as you lean the bike over, V-Block Technology on the rear for straight-line drive out of ruts, and Reinforced Scoop Technology (RST) to stop the blocks tearing out under hard acceleration on loose ground. The carcass also gets a rounded sidewall profile, which Dunlop says improves compliance over roots and rock ledges instead of just skating across them.

Roberto Finetti, Dunlop’s motorsport lead, frames it as an evolution rather than a reinvention: the EN92 “continues to build on the proven success of Geomax EN91 to offer riders even greater performance.” The EN91 wasn’t a bad tyre to be compared against — it was on the bikes of multiple Enduro European and Junior Enduro World Champions.

What we know / What’s still unclear

What we know: - The EN92 replaces the EN91 as Dunlop’s flagship FIM-spec enduro competition tyre. - It’s available in a medium compound and a new EN92 SOFT compound. - European sizing covers a single front fitment and two rear fitments, split across both compounds. - It debuted publicly at the 2025 ISDE in Bergamo before this wider rollout.

What’s still unclear: - Dunlop hasn’t published pricing for any market, EU included. - No confirmed on-sale date beyond “early 2026” rollout — dealers may see stock at different points through the year. - No word yet on sizing or availability outside Europe.

Why this matters if you’re not a factory rider

Most of us buying enduro rubber aren’t chasing an ISDE gold medal, we’re trying not to loop out on a wet fire road in the Ardennes with a credit card bill from last month’s gear order still open in another tab. A dedicated soft-terrain option instead of one compromise compound is the kind of change that shows up less in lap times and more in not casing a root ledge on a Sunday you promised yourself you’d actually go ride instead of just talking about it.

The riders who’d actually notice the difference between EN91 and EN92 on a wet rock section are the ones at the sharp end of events like Red Bull Romaniacs, where Manuel Lettenbichler’s record-equalling seventh win this year came down to exactly this kind of terrain — greasy roots and loose rock ledges where tyre choice is the difference between a good line and a long walk back to the truck.
