great sprockett
mounted right up to my ssr125 no problems, the only thing is i wish the bolts was slightly shorter, but a angle grinder fixed that issue.

Perfect to get 50mph out of the X1 Spark and similar emotos 60v+
This fits the emoto rims great! Make sure you get the appropriate sproket for the rim.
