AmSnow.com is now SnoWest.com
The snowmobile world recently saw two of the most technologically advanced snowmobile engines ever built released in the same model year. AmSnow already put the Yamaha Sidewinder’s Genesis 998cc 4-stroke on a dyno, but DynoTech Research was equally excited to see what the new 850cc direct-injected 2-stroke E-TEC motor from Ski-Doo and Rotax would do. We were not disappointed!
