[QUOTE="Aust 520exc, post: 156107, member: 23806"] I guess I am leaving myself open to attack, but a two stroke generally makes more power (HP) and torque than the equivalent cc four stroke. Most people make the mistake of confusing torque with the flywheel effect. The reason that a two stroke "feels" like it has no torque is because most two strokes have less rotating mass - lighter flywheel - than four strokes, as they fire twice as often and don't need the extra rotating mass to keep the engine running. Due to this extra rotating mass a four stroke will pull from a lower rpm and feel "torquier" than a two stroke. If you ride a YZ426F and then jump on a WR426F, which one feels like it has the most torque – of course its the WR, it has a heavier flywheel, which stores power – also makes it slower reving.
