Dunlop Geomax Enduro EN91 review [Dirt-Ready Dual-Sport Tires]

We are wary when we see “FIM approved” on an all-terrain tire. Over the years, we’ve generally found them lacking for jumpers, even though conservationists think they’re hunky-dory. However, the Dunlop Geomax Enduro EN91 changed our minds. Maybe Team USA knew something when they selected the EN91 for the 2019 International Six Days Enduro and took the win.Keep in mind that the Dunlop EN91 is not necessarily sold as a purpose-built off-road tire. It’s DOT legal – a godsend for those who don’t like the idea of ​​installing a tire that could get them a ticket when racing down the street. When we replaced the stock adventure style tires on the 2022 Husqvarna FE 350s, which are only there to help meet DOT noise regulations, we wanted to stay on the right side of the law and mounted a pair of EN91s on the Husky dual-sport bike. We went with the narrower 120/90 x 18 in the rear – there’s only one front, a 90/90 x 21. To keep things in the family we used Dunlop Heavy tubing Duty MX. For riders who want a larger rear footprint, there is also a 140 rear.dunlop describes the EN91 as a “hard terrain” tire. However, we’ve used it on everything from pavement to sand—it’s a dual-sport tire, after all. The EN91 uses Dunlop’s “Block-In-A-Block” technology on the side buttons, which we’ve had good luck with on pure off-road Dunlops, including the Geomax AT81 and MX33. Although the Geomax EN91 has the required 15mm shallow buttons. , as required by the FIM, the widely spaced knobs look much more like a dirt bike tire than the typical dual-sport tire, including Dunlop’s venerable D606, which has knobs a third higher and closer together. It didn’t take long for us to be sold on the Dunlop Geomax Enduro EN91 tires in the dirt. After a few kilometers to familiarize ourselves, we started to push the limits of the EN91. Impressively, the EN91 responded with confidence, providing great feedback and totally predictable mannerisms.Climbs in California can be mixed affairs, with loose stones, rocky ledges, hardpack, soft dirt and sand on the same grade—a challenge for any rear tire. The EN91 immediately gave her confidence, as she didn’t seem to be bothered by the changing traction conditions. Yes, we were on the wonderfully smooth Husqvarna FE 350s, which helps. Yet the EN91 still responded as expected. The side knobs came under scrutiny, as we hugged the sometimes hard/sometimes soft cambered sides of the hill. The front and rear EN91s hook tenaciously to the side, yet allow for the constantly modulated acceleration needed to roar confidently to the top of the mountain. The rear EN91 has something Dunlop calls Tilt Crown Block technology. Basically this means that each row has different button angles. According to Dunlop, if an angle isn’t quite right for a specific condition, another button will take over, especially in rocky terrain. Considering the rear EN91’s rock-climbing performance, we find it hard to dispute that claim. Dunlop claims this tread pattern works for mud. However, now is not the right time of year for us to test this.The Dunlop Geomax Enduro EN91 front end is a tacky design. In cases where we thought we were going to lose the front end, the EN91 responded with uninterrupted traction. It is indifferent to the type of terrain, always resistant to washout. The sidewall pull is particularly noteworthy – Block-In-A-Block isn’t just advertising language, as it works, even with shorter buttons. Transitions are handled quite easily at both ends. Again, in Southern California, conditions can change instantly, so an adaptable tire is essential. The EN91 acclimatizes perfectly to change, making it easier to concentrate on the job at hand, rather than worrying too much about the action of the rubber. Braking is predictable with EN91s, with the front tire doing more than its share of the burden. The back can slide out if needed, no surprises.With the shorter knobs, we expected it to be a bit easier to steer with the rear tire on smoother, dual-sport-appropriate dirt roads. However, we had to be more aggressive than expected with the throttle on the Husqvarna FE 350 to get the backend out of the rides. Again, part of that is due to the smooth nature of the DOHC powertrain. We expect a 500 to light up a 140 rear a little easier. On the pavement, the Dunlop Geomax Enduro EN91 is as good as you can expect from such a legit post. The shorter knobs have a lot of corner balance, as the front and rear EN91s provide useful feedback. Again, the braking is predictable, and no tire slipped on the road, even during emergency braking.In one instance that eluded us, we didn’t miss our turn on Angeles National Forest 6N07, a particularly long and rocky road uphill from Bouquet Canyon that the EN91s handle wonderfully. A few hits on sharp rocks kept our fingers crossed, but the Dunlop tubes still held their own – phew! We haven’t done enough miles on the EN91s on pavement to assess wear, although they’re not really a tire you want if you’re planning on giving them a lot of road going go for the D606 for it. We were absolutely pleasantly surprised by the EN91. Previous FIM-approved tires left us wanting more, but these tires delivered in the dirt in a wide range of encounters. We’d still stick with an all-terrain tire specifically designed for dirt performance if we weren’t concerned about the Mounties. However, if we are to be legal, the Dunlop Geomax Enduro EN91 doesn’t feel like we’re giving up much on a dual-sport bike.
