Malossi mhr RHQ 12mm crank convertion small end

Hey. Im going to buy a new crank to my aerox. I want the malossi mhr rhq 12mm crank, is it possible to fit mhr replica 10mm cylinder kit with a convertion small end bearing 10x17x16? Unfortunately the sylinder kit only comes with 10mm piston gudgeon pin. Or do I have to buy a separate mhr replica piston with 12mm gudgeon pin?
Cant find a convertion small end bearing with dimention 10x17x16.

 

im pretty sure you could get a bearing made up to fit. try maybe SKF bearings. i had this problem at work building some scooter engine, i ended up routing through all the parts boxes and found a bearing that was the right dimensions
