Lightened flywheel:
Advantage:
-quicker ramp up
-quicker ramp down
-quicker shifts (downshift: rev drops quicker due to higher relative friction = quicker shift)

Disadvantage:
-engine runs "rougher", higher rotating mass smooths out power
delivery.
-lower durability
-clutch ingagement needs to be more precise.
-rougher power curve (per cycle) = higher accelerations of piston
= higher loads on pins.
