Snowmobile Gear Ratio Calculator

Here’s a simplified table based on estimations:

Speed (mph)	Engine RPM (est.)	Track RPM (est.)	Gear Ratio
10	3000	500	6:1
20	4000	800	5:1
30	5000	1200	4.2:1
40	6000	1600	3.75:1
50	7000	2000	3.5:1
60	8000	2400	3.3:1
70	9000	2800	3.2:1
80	10000	3200	3.1:1

These ratios are estimates and can vary depending on the specific make and model of the snowmobile, as well as other factors like track size, engine displacement, and clutching systems.
