Depending on its displacement, a 4-stroke’s power curve tends to favor higher torque output at primary clutch engagement RPM.
Some of this is affected by the fact most 4-strokes use more displacement to get the same horsepower.
For instance: A 600cc Polaris 2-stroke and a Cat-Suzuki 1,056cc 4-stroke make around 125-hp, however, there’s a big difference in torque between the two, particularly in the lower RPM ranges.
It’s a fact that 4-stroke snowmobile engines live a longer life before there’s major maintenance needed. Meanwhile 2-strokes will inevitably need a top-end rebuild once the miles get into the teens.
NO CARRYING OIL:
Since a 4-stroke is not consuming its oil the way a 2-stroke does, you don’t have to carry any when you’re on a long trip or spend extra riding time looking for a place to buy more oil to top up.
ELECTRIC START AND REVERSE INCLUDED:
Going back over the last 14 years, you’ll be hard pressed to find any 4-stroke sled that doesn’t have both ES and reverse. Not so with 2-strokes.
Although the initial cost of a 4-stroke may be higher, you generally get the money back and more when you go to sell a used 4-stroke sled in good condition.
