Snowmobiling blues...

Never been on or around a snowmobile. Wouldn't get to use one much here in Oklahoma! MAYBE once a year if I'm lucky.

Are all of the newer ones 4 stroke? Is 4 stroke preferred over 2 stroke? I LOVE 2 stroke 4 wheelers and currently have a Yamaha Banshee with CPI pipes, the sound and sudden power delivery is so addicting. I would like to make a trip somewhere and go ride a snowmobile for a few days.

Bombardier has 2 strokes and 4 strokes models.
Yamaha has 4 strokes only
Polaris if I not mistaken are 2 strokes only.

2 strokes are best for off track (deep snow) machines where raw power and light weight are preferred.

4 strokes are best suited for Grand Touring machines.
