a consentric drive xplorer 400 has 25 fronts and 25 rears 2:1 front diff ratio and 13/36 rear sprockets

a consentric drive scrambler 400/500 has 23 fronts 22 rears 2:1 front diff and 13/36 rear sprockets

both have the same trans ratios for hi and reverse so what gives with $x$ why doesn't on machine have any binding issues ????

I would like to install a xplorer trans in my scrambler and a set of 24 inch tires on the rear
I assume I should change the ratio of the sprockets but looking at the specs on these two machines I guess I neednt bother???

anyone know whats up???

 

I have no IDEA what gives I checked the ratios in the transmissions and they ae both identical the ratio of the transfer sprockets and the pinion and snorkle gears ??

one of the two systems must be turning at different speeds

makes no sense
