• Poll: 2-Stroke or 4-Stroke Engine

The debate of 2-Stroke vs. 4-stroke engine in snowmobiles has been ongoing for decades and has heated up as new technologies emerge on both platforms. 4-strokes have become lighter while 2-strokes are more fuel efficient and cleaner.

Advantages of 2-Stroke Engines:
Small, light, fewer parts
Less costly to manufacture and repair
Mechanically efficiency, less friction
Power stroke for each revolution of the crankshaft
High horsepower
Easy to start


Advantages of 4-Stroke Engines:
Durable, less wear and tear, long engine life
High thermal efficiency
Runs cooler
Quiet operation, less noise
High torque at low RPM
No oil loss

In the end, it's up to the customer to decide which they prefer.
