Is a 2002 Suzuki quad a 2 stroke?

The 2002 Suzuki quad, specifically the Suzuki LT-Z400, is a four-stroke ATV. Suzuki does produce two-stroke models, but the LT-Z400 is not one of them. If you have a different model in mind, please specify, as there may be variations in Suzuki's ATV lineup from that year.
