The KTM 85 specs that plug and we have ran BR9EG for years with no issues at all. Buy them by the case........

I searched more and while not positive on differences I believe its iridium and the vx is the strap is v shaped.
Correctly jetted I shouldn't need one too often...but it's not there yet. I use to run ND hot-V plugs years ago with success,,took longer to foul compared to ES EV or champions in my trail bike,so I'm confortable in quality. I price shopped and went with 4- Densos 5392 (same as IWM27) for 32.08 on fleabay fast shipping included. .

I considered the BR9eg,,but the br9ecmvx and I believe the denso 5392 has a shorter porcelain. It's tight under the gas tank and shorter does make it easier to get my plug wrench on the shorter plug.
Thanks for ideas

Stock plug. Once jetted correctly and running a good fuel I was able to run a single plug for 10-15 hours. Which on that bike is an entire summer for me.

Our 13 125 called for a br9ecm (I think it was a 9) and I always used a br9es, the ecm is just a shorter plug to make it easier to get wrench on it
