The 2017 Moto Guzzi MGX-21 Flying Fortress
The 2017 Moto Guzzi MGX-21 Flying Fortress arrived as Mandello del Lario's answer to the American-style bagger, built around the brand's biggest V-twin and dressed in aggressive, angular bodywork that looks nothing like a traditional Guzzi tourer. This is a bike built for boulevard presence and long, low-effort highway miles rather than backroad carving. The transverse V-twin layout means shaft drive and a wide stance, and that low-rev torque delivery makes it feel unhurried at cruising speed, pulling hard well before redline rather than demanding you chase revs. The 21-inch front wheel and stretched silhouette are the visual signature, and they shape how the bike steers at parking-lot speeds as much as on the open road. As a first-year model, the 2017 MGX-21 Flying Fortress introduced this platform to the lineup with no prior version to compare against, so early buyers were evaluating a genuinely new design rather than a refinement. This appeals to riders coming from Harley-Davidson or Indian baggers who want something mechanically distinct and less common at bike nights, with collector interest currently low but the styling distinctive enough to hold niche appeal.
