4 stroke

1. 4 stroke runs on straight gas, 2 stroke runs on a mix. 2. 2 strokes would be overall stronger then 4 strokes because in a race theres two classes (125 2stroke - 250 fourstroke) and (250 2 stroke - 450 4 stroke) the four strokes have to double there engine size to compete with 2 strokes. 3. 4 strokes have more useable torque, 2 stroke has a strong kicking powerband. 4. 2strokes all around are cheaper then 4 strokes. 5. 4 strokes are usually bigger. I've ridden both 2 stroke and four stroke and i'd have to say i like 4 stroke better. 2 stroke Good : -alot of power - smaller and lighter - cheaper Bad: - spark plug fouling - pre mixing gas - not as efficient - not as durable 4 stroke Good: -lots of torque -straight gas -more powerful -sounds better then a shrieking 2 stroke Bad: -loud -big -expensive -heavy
