Anyone have a part number for a compatible aftermarket rear sprocket?
OEM part is 3XV-25437-40-00 (37T & 520)

I've read that one from a TZ250 V-twin can be made to fit but requires drilling the mount holes out to 10mm. I'd rather have a bolt-on that doesn't require modification, if possible.

I have the front figured out. Seems to be the same as some of the WR models. :thumbs: And the chain is a 520-110L.
