No more 2-strokes in Indonesia
Indonesia will soon ban the sale of 2-stroke motorbikes, meaning the TS-125 trail bike, that is very popular here will be out of dealerships. Not being a mechanic myself, I can’t really give you the inside scoop on what the difference is between a 2 stroke and a 4 stroke, other than the 2-stroke needs oil to function. Its very easy to tell the difference in the street, because 4-stokes have a low sounding engine, and 4-strokes have that high pitched whine.
Mick Turnbull has a 2-stroke Aprilla 125, with a top speed of 180km. People tell me the 2-stokes have more zip, but they leave a nasty trail of fumes behind. The US and other western countries banned 2-strokes years ago and Indonesia is finally getting with the program.
Air pollution in Indonesian cities is bad and is a time bomb for bad health. An expat told me that you can walk around in Jakarta all day without getting sunburn because of the smog layer! Bandung is another place that is getting bad. Locals here in Bali buy 2-stroke scooters because they are a couple of million rp cheaper than a 4-stroke.

That is excellent news, though expect older 2 strokes to be grandfathered–an outright ban would remove most bikes from the roads, which means 2 strokes will be around for years to come.
Mechanically the main difference is that a 2 stroke fires (burns gas and air) every time the piston goes up, meaning it burns more gas (and results in more emissions) than a 4 stroke, which fires only every other stroke.
It’s not just the air that will get a break but our ears–2 strokes are incredibly noisy–think of a mobile chain saw and you get the idea. Thank God their days are numbered, especially on Bali!!
I’ve shipped a vespa super 150cc from the year ‘77 from Bali to Belgium. And this 2stroke may make a lot of noise, it sounds great!
viva vespa!
i love 4-stroke verry much they are great compared to 2-strokes.
I think its the number of strokes the piston makes up and down in the cylinder.
With four strokes 1.The piston gets pulled down and fuel is squirted in 2.The piston goes up compressing the fuel 3.A spark ignites the fuel pushing the piston down 4.Piston goes up pushing out fumes. At least that’s what I think happens.
Two strokes have petrol and oil mixed together.
