WEIGHT:
Probably the single biggest attraction with a 2-stroke is its ability to generate plenty of power from a lightweight power source.
Most 2-strokes make similar power to 4-strokes nearly twice their displacement and using several times more parts.
COLD WEATHER STARTING:
Historically, 2-strokes, particularly those equipped with EFI, have been sure bets to start in extreme low temperatures. This is not always the case with 4-stroke sleds.
SIMPLICITY-COST EQUATION:
There are far less parts in a 2-stroke engine than in a 4-stroke. Although maintenance may be required at a younger age, the parts and labor cost to do a renewal is far less than on a 4-stroke when major work is required.
FUEL MILEAGE:
Unbelievably, fuel consumption on the newest generation 2-strokes is the same and often slightly better than on comparable output 4-strokes.
LOWER PURCHASE PRICE:
2-strokes generally cost several percentage points less than a 4-stroke with comparable power.
