Slight Diviation but are the twin shock Dt 175 swing arms the same as the YZ125a ? IF i put them side by side they do but maybe i need glasses.
are you talking about the bushes or the swing~arms?
not too sure about the bushes but i have a DT125c and DT100a and both swingarms are the same as each other but are HEAPS DIFFERENT to my MX125a swingarm.
my MX125a swingarm is longer and wider at the pivot point than the DT swingarms.
i'd suspect the YZ125a swingarm to be the same as the MX.
basically, the YZ/MX frame is "wider" at the swingarm pivot point.
i think you'll find the left/side engine case on the YZ/MX is also "wider" by the same amount and the countershaft is "wider" as well.
theres only about 7mm~ish {can't remember exactly} in it.
