2-strokes are dying a slow death. 4-strokes are so much better! A lot less maintenance! 4-strokes can be raced or trail ridden without no modifications! 4-strokes are not as loud as 2-strokes. 2-strokes you have to ride hard. 4-strokes you can ride fast or slow low rpm mid rpm or high rpm. 2-strokes have a powerband. 4-strokes don't! About the only thing a 2-stroke has on a 4-stroke is that it is lighter. 2-strokes you have to scream at high rpms!
