I just received an email back from Sunstar about the sprocket size. This is it:
This has turned into an interesting question actually.
I’ve been researching it and it looks like this may be mis-listed in our catalog. We show our 320xx front sprocket for the NX but I’ve checked a couple of our competitors and compared the specifications and it looks like the total height, with the embossed side of the sprocket should be 10mm and our 320 is only 7.8mm.
Do you have the OE part that you pulled off where we can check the measurement with a set of calipers? I’m guessing its supposed to be 10mm and ours is listed in error but would need to check against the OE part to be certain.
