This is a lightweight two-piece rotor that is compatible with genuine wheel specifications. The total weight of the front and rear rotors is 2560g lighter than the weight of the entire vehicle, and the unsprung weight is more than twice that, at over 5kg. This weight difference is the greatest advantage for light vehicles, and it provides light movement in all movements during acceleration, deceleration, and cornering. It is a bolt-on genuine replacement type, so it can be easily replaced. The racing special cast iron material and six curved slits provide the best braking performance even when replacing with sports material brake pads. The bell color is a lightweight type that uses a center bell hat made of lightweight duralumin material, and can be selected from three colors: black, silver, and gold. Red and blue are added to the custom colors separately.
It is introduced on Ameblo's "M&M HONDA's Honda Honki."
