Not really! Not like a two stroke anyway. When you put a cam and pipe on them they have a really hard hit from midrange up so some people might call it that. It's mostly torque!

yeh they have a "power band". it's control by the thumb actuater on the right side of the directional controls!!!!!



just kiding: power band like you are thinking is on a 2-stroke engine.

250r
yz125

these type that "mix" fuel. a"4" stroke has a more gradual power band that will allow you to lug in gears and not stall the motor

Power Band: subjectively defined rpm range where your engine produces a substantial portion of its peak power. The power band usually extends from slightly below the point of peak torque to slightly above its peak. The motors (internal combustion reciprocating) we are dealing with here all have a “power band”. Four stroke motors generally have a broader power band or torque curve than two stroke motors.

I believe He is one of those who thinks a power "Band" is a physical part inside your engine. :D
