I am not sure what the translation in English is, but does anyone know what the original reductionratio is from gearbox to rear wheels?
In my present config it is 42-21.
I want to know what this should be in the original setup.
many thanks

US 1750s are 4.56 from driveshaft RPM to axle/wheel rpm. I would guess all 1750s had this same ratio, but am not certain. 42-21 gives 2.0, which can't be right. Is it 4.30? There were such axles.
