Vehicle Information
Arctic Cat El Tigre 250 Snowmobile (1973-1975)
The Arctic Cat El Tigre 250, produced from 1973 to 1975, was a performance-oriented snowmobile powered by a free-air cooled Kawasaki twin engine, typically ranging from 245cc to 250cc. Known for its agility and spirited performance, it catered to riders seeking a competitive edge on the trails. A notable evolution occurred in 1975 with the introduction of the El Tigre Z 250. This specialized model was designed for serious riders and racers, featuring competition-oriented upgrades such as a distinctive black tunnel, lightweight chassis components, and an engine optimized for speed and rapid acceleration. While the core 245cc Kawasaki twin, free-air cooled engine remained largely consistent for the 250cc models in 1973 and 1974, the 1975 'Z' variant represented a significant performance refinement.
