125a st rear sprocket

[Freakshow]

just bought one of them dished rear 125 sprockets, but noticed the 125 c is the same style.  question is are the rear wheels the same also and will they and the backing plate slot straight in the 125 A 

also the 401 part is a 47t and is steel, are the 453 rears steel too are are they alloy ? and if so with the same bend ?

The hubs are interchangable, but not the same. The early bikes have 8mm bolts (12 or 13mm heads), whereas the 125C has studs (can't recall if they're 8 or 10mm, but I think 10mm). Nothing that a few minutes with a drill can't fix... (or the correct rear sprocket if you're going the other way).

Rim offsets are the same, I think. I know that the 125D+ wheels and the monoshock DT wheels have a different offset, but I'm pretty sure that the earlier ones are fine.

Backing plate is definitely interchangable. Theres a ton of different part numbers, but all of the twin shock 125/175s and YZ125C/X brake plates are interchangable.

Axles are all the same diameter, so no drama there.

ok cool.  though you might know.

just saw a YZC wheel for less than i paid for the sprocket so i though it might be a cheap option or spare
