I have recently bought a second hand original accessory Yamaha Top box & it is made by MBK. The base plate it requires looks like a Givi Mono Key plate but it will not fit on the Givi plate i have as the 2 "pins" that fix into the top box are too far apart. I have tried my local Yamaha dealer & sent a email to Yamaha but as yet have had no luck in finding a plate. I have searched the internet to try & find the company that made them MBK but can find nothing relating to top boxs. Can anyone throw any light on this??? Regards Steve
