Whats the difference between a 125cc 2stoke or 4 stroke?

Answer 1

A 2-stroke is a simplier engine with fewer moving parts. A two stroke is a higher revving engine, which also means engine parts need to be replaced more often, like pistions and rings. A four stroke creates more usable power and you're able to lug and engine down more. I've have two 2-stroke motocross motorcycles then switched to a 4-stroke. I've never go back to a 2-stroke. A four stroke is easier to ride and has a better power band. Also my tires, chain, sprockets last longer. Along with not having to replace the piston and rings all the time. It's cheaper in the long run. 4-strokes are also more fuel efficient and don't produce as much smog. Another post stated a lawn mower is a 2-stroke, that is wrong. Lawnmowers are 4 strokes. Leaf blowers and weed eaters are usually 2-stroke since 2-stroke engines are lighter and you have to carry those items around to use them.

Answer 2

A 2 stroke engine is similar to a lawn mower the intake of air and the intake of gasoline happens simultaneously, and the outtake and exhaust is the 2nd stroke,, while a 4 stroke has the compression of the air and gas to increase power. It's more complex, but more effective.

Answer 3

2 stroke engines fire every time the piston comes to the top of the cylinder, 4 stroke every other time. 2 stroke engines rev higher. Most 2 stroke dont use valves either.

Answer 4

Two strokes are quicker than 4 strokes, they are also noisier, and you need to add 2 stroke oil to to petrol, so they are smellier.

Answer 5

first, post your question in the proper category (this is cycling, as in bicycling, not motorcycling)

second, talk to a mechanic
