People ask all the time what the differences are between 2stroke and 4 stroke 50cc mopeds or scooters. Without getting into engine terminology the best way to explain it is: 4strokes work best on flat ground as they lack the bottom end torque that is needed to climb hills. The two stroke is best suited if you live in a hilly area as they will climb a much steeper grade of road. Additionally there are maintenance differences between each moped or scooter. The 2stroke requires oil to be added into the fuel prior to entering the carburetor. This can be done via the old method: premixing or via the new method: oil injection pump. The new method which is featured on most mopeds or scooters has an oil reservoir and a pump that adds the oil to the fuel system as it enters the Carburetor. The 4stroke motor is just like you car with an oil pan full of oil that needs to be changed every 1000+-.
So here in a basic list are the pros and cons of each style of moped or scooter.
2stroke 4stroke
pros: better for hills, faster don't have to regularly fill up oil, less pollution
simple engine, easier engine upgrades longer life span (due to slower motor)
Cons: more common engine failure less capable on steeper hills, regular maintenance strictly adhered to.
constant oil adding, noisier more expensive engine upgrades, complex motor.
Results: for those of us driving on flat ground with our moped or scooter as a run around commuter EX: Waikiki. The 4stroke engine is best suited. If you live up in the hills of Honolulu or intend on taking your moped around the island of Oahu on the weekends 2stroke models would be your best bet.
We at pacific mopeds carry both so check us out when looking for a moped in Hawaii.
