Not sure which size sprocket will work best on your FW11? Give in to the intrusive thoughts, but them all! (At a discount of course, we aren't savages)
These sprocket supports usage of a #35 chain on a Sotion FW11 & FW11 Mini motor. The #35 is a popular upgrade for high powered razor bikes, and also is the factory chain size on the Burromax TT1600R.
