i have an 01 kx125 and would like to get a cheaper plug than the 10$ one the dealer recomends. What are you guys running/do you suggest?

 

i had ngk's in mine that i paid about $6-7 for. and i loved them, ngk are some whoopass plugs.

ngk makes alot of plugs, which one(s)?

 

BR9EIX / BR9EV

 

For your bike, NGK recommends BR9EIX

For most 125's a heat range in the "9's" is good ie...BR9EG or BR9ES, a BR8 plug is normally for a 250.

B= 14 mm thread diameter
R= Resistor Plug
9= heat range
E= 19 mm thread reach
S= Racing plug

I plagiarized this, I'm not really that smart But Google is awesome if you know what to put in the search bar.
