Is there a steel sprocket available, possibly from another model, that will fit a YZ125C.
Not so much worried about weight but trying for a longer life
The standard sprocket is dished and the owner doesn't really want to make a spacer to fit a flat sprocket.
Thanks

MX125/175A has a dished steel sprocket. They're probably harder to find than the YZ alloy sprocket though - at least there's after-market dished alloy sprockets out there...
The spacer is a better option. DT175 sprockets would have to be THE most readily available sprockets in the world.

Thanks nathan,
I don't know why he's worried about the spacer, I'll have to make the bloody thing!
Truth is I get to ride the bike often enough so I certainly don't mind

Other options:
YZ125X rear wheel will go straight on, and takes a flat sprocket. Rim is a straight walled lipless type, unlike the C's externally lipped rim (if that matters).
YZ125D/E/F, IT175D/E/F or monoshock DT125/175 rear hub can be machined down to the 125X dimensions. Obviously these are a lot easier to find than YZ-X wheels.

very easy Brent,
roll on down to your Yamaha dealer and tell him you want a sprocket for the good old Ag 100.
available in either 47t or 51t in good old hardened steel.
only catch is, the MX/YZ style has a 6 bolt pattern while the Ag has a 4 bolt pattern.
bolt P.C.D. is the same and so is the centre hole and dish.
i just bolt the 2 sprockets together then drill through the 6 bolt one into the other. a 10minute job with the right drill press.
thats what i use on my little MX125 and it's the same rear hub as the YZ125c.

Thanks guys,
There's a DT175 at the local dump shop for SFA. It's got hubs so I'll grab that this weekend.
And we now have a few options
