Happy Holidays Beeb, Need help identifying a 5 spoke Marchesini Wheel. Was purchased used for a YZF750, it fits the axel fine, but the rear rotor is a 5 bolt setup rather than the YZF750 6 bolt configuration. I'm not experienced with OEM Marchesini's, do they use a custom 5 bolt setup or an adapter or do they usually use the OEM rear rotor? Can anyone break down the part #'s on the photo? Any assistance is appreciated! JB
