Dirt Bikes FAQ
What size dirt bike should a beginner get?
Most adult beginners do best on a 125 to 250 cc four-stroke trail bike with a seat height they can manage with at least the balls of both feet on the ground. These bikes deliver smooth, predictable power that builds skill without punishing mistakes.
Is a two-stroke or four-stroke dirt bike better?
Two-strokes are lighter, simpler and deliver explosive power, but they need more frequent top-end rebuilds. Four-strokes have smoother, more usable power and longer service intervals, but are heavier and cost more to rebuild. For most beginners, a four-stroke is the easier choice.
