About GAS GAS

Country of Origin: Spain
Founder: Narcís Casas & Josep Pibernat
Best Known For: World-class trials bikes and competitive enduro/motocross machines; later KTM Group era

Company History

GASGAS was born in Catalonia’s trials heartland in the 1980s, when dealers Narcís Casas and Josep Pibernat turned their experience supporting riders into a purpose-built brand for observed trials. The early TXT models balanced featherweight agility with tractable torque, letting riders hop, pivot, and climb with uncanny control. Success in trials bled into enduro and later motocross, where two-strokes like the EC series earned reputations for crisp response and neutral handling on tight Iberian terrain. Financial turbulence in the mid-2010s led to restructuring, and in 2019 the KTM Group acquired and relaunched GASGAS globally. Under the red livery, modern GASGAS enduro, MX, and cross-country machines share core platforms with Austrian cousins but retain their own setup philosophy and playful brand voice. Trials remains a pillar, with competition-proven bikes that continue Spain’s dominance. The rally program—including Dakar entries—underscored the new era’s ambition. Historically, GASGAS represents the Catalan craft of light, communicative chassis that reward technique, and the brand’s second life shows how heritage and scale can coexist: a boutique trials specialist that grew into a full-line off-road contender without losing the fun, free-riding personality that made it famous.
