Monza Junior 160 Output Sprocket

[Honduc]

Hello, I have been riding and building bikes all of my life, this is the first Ducati I have owned. it is about half of a 66 Monza Junior and I have a question: is the output sprocket (front sprocket) the same as the 250 and larger singles?

dont know about the 160 cc but the 125 uses a 420 chain and the 175 thru 350 cc uses a 428 chain . pitch is the same on both sprockets but the 420 item is smaller . a 428 sprocket would fit a 125 tho .

thanks, the 160 is supposed to be an overbored 125 so I think the bottom ends should be the same

[Eldert]

the splines on the outputshaft are al the same . you can fit a 420 , 428 or a 450 's 530 sprocket .
they al fit .
