Vehicle Information
Ski-Doo Alpine 508 Snowmobile (1990)
The 1990 Ski-Doo Alpine series represents a line of robust utility snowmobiles. The "Alpine 508" designation typically refers to models equipped with a 506.8 cm³ two-cylinder engine, delivering power at 6500 RPM. During this year, the Alpine range also featured other engine options, including 497cc/496cc fan-cooled Rotax engines found in trims like the Alpine II (model 3350) and Alpine IV (model 3351). A notable development for the 1990 Alpine series was the limited introduction of a 580cc 4-stroke Rotax engine in some Alpine IV models, marking a significant technological shift towards reduced noise and emissions. Additionally, a mid-production modification saw 26 out of 50 Alpine 4 units converted to Alpine 2 models, indicating internal adjustments within the lineup. These changes highlight the evolving nature of the Alpine series during this period. FAQ:
