Hello Robert,

I don't have the info immediately to hand, but I fitted a new chain and sprocket to my 125H so if you haven't found the size you want I will find my receipt and let you know. I fitted if I remember correctly a Reynolds chain but its a while ago now so will confirm when I find the bill.

Regards
Leonard.

chain size is half x five sixteenths inch.

not sure why its imperial for an Italian bike but that's what the blue book says.

the drive sprocket has 14 teeth, not sure if its possible to get them in different sizes but I suppose its possible to have any size machined up.

Hope this helps.

Regards
Leonard.

The same reason the wheel rims are in inches?

Historic.
