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.

Appears well made.
Shipping time expressed was actually faster than they claimed which was like around 2 months. It arrived in like 2 weeks if I remember right. Either way I was surprised to see the package arrive when it did. Understand that I couldn't even find another anywhere, so... I'm pretty happy. :)

Meh
The holes that are drilled are off center. Attempted to drill them out like other reviews said, and the sprocket ended up being unbalanced. Without modification, will not fit a grom clone. My clone is a 22 RPS Condor 150cc.
