As the third 350cc four-stroke cross-country motorcycle under the Austrian umbrella of the Pierer Mobility Group—the other two being the KTM 350 XC-F and Husqvarna FX 350—the GasGas EX 350F is the one and only 350 model in GasGas’ 2021 lineup as it currently does not offer a motocross version, nor does it produce four-stroke enduro models or dual sport bikes. So a model similar to the KTM 350 SX-F, Husqvarna FC 350, KTM 350 XCF-W, Husqvarna FE 350, KTM 350 EXC-F, and Husqvarna FE 350s is currently out of the question. In the racing world, the EX 350F will be in very capable hands with Ricky Russell, who will campaign the bike in the 2021 Grand National Cross Country (GNCC) and AMA National Enduro series for the Coastal GasGas Factory Racing team.

We have begun testing the EX 350F for the first time, but before we got it onto the trails and track, we ran it on our in-house Dynojet 250i rear-wheel dynamometer to see what it was capable of in a strictly empirical sense. After mounting a Dunlop D404 street tire on the rear wheel, we documented peak figures of 48.9 hp at 11,800 rpm and 25.3 pound-feet of torque at 8,800 rpm. For comparison’s sake, the 2021 GasGas EX 350F makes 0.2 peak horsepower and torque less than the 2020 Husqvarna FX 350.
