Here Ive decided to list a bunch of spark plugs that work with pitbike engines from 50cc to 140cc and beyond. This list is from experience of plugs I have used in the past upto this present day and with the help of a plug cross reference. Any other plugs that are compatible I will add here.

In no order:

NGK CR6HSA
NGK CR7HSA
NGK Iridium CR7HIX
NGK C7HSA
Torch A7TC

Recommended spark plugs are:

NGK Iridium CR7HIX, NGK CR7HSA, NGK C7HSA

Note: The R stands for Resistor and might be helpful for you to have a spark plug with an "R" in it to stop the spark interfering with electrical components aka bicycle speedo's, digital RPM & temp readers ect....

There is the myth that you can use any spark plug. while this almost being true you SHOULDN'T do this as it can lead to melting plugs, bad timing, not wanting to run and wont do your engine any good, however you can use it as a means to find out if your bike is has spark or not/ to find out if the bike will start.
