Here's a description from Honda of UK: A Light-weight Forged Chrome-Molybdenum Steel Flywheel A super-light flywheel made of chrome-molybdenum steel gives the Type R a smoother power transition between the K20A engine and the Type-R close-ratio 6-speed transmission. The lightened flywheel improves both the feel and performance of the engine. It gives an instant response at any sudden throttle, when acceleration is demanded at any time as driver steps on the metal pedal. It reduces about 0.3 seconds in accelerating from 0 to 100 km/h, which equals to a reduction of 50 kg in the car weight.
