I'm considering a 50cc scooter. Which kind of motor is more powerful: 2 stroke or 4?

A 2 stroke 50cc is kind of like having a 100cc 4 stroke. It makes power on both the up and down stroke. A 4 stroke makes power every other stroke.

WHile I have to agree, 2 stroke is likely going to have more high rev power, they tend to be less reliable and more "touchy" than 4 strokes. ALso, the life expectancy or a two stroke is significantly less than a comparable 4 stroke. That being said, 2 strokes are easier and lighter to work on. Good thing too. Providing you can get parts.

Like GOBs used to say,"Four strokes are for machines, Two strokes are for toys." Me I like my toys, but they're not for everyone.

i would skip the 50cc 2-stroke and go 4 a 150cc 4-stroke...i have a 2-stroke yamaha banshee (350cc) and 200cc 4-stroke dirtbike and the 4- stroke is significantly better torque but more speed with a 2-stroke...its all preference....

50cc bikes are considered "moped" in Texas. I think they require no license or insurance.

Does that mean I'd have to register and get insurance for a Vento Zip R3i?

By the way, how is the acceleration on a lighter-weight 50cc two stroke compared to a heavier-weight 250cc motorcycle?
