Yeah most street bikes, except way back are 4-stroke.  Now even motocross bikes are 4-strokes.  Kinda miss the power band of a 2-stroke.
knowledge: Two-stroke engines often have a high power-to-weight ratio, power being available in a narrow range of rotational speeds called the ''power band''.
response: I see, the two-stroke engines have indeed more a power-to-weight ratio that is high, the power is available in the power band
