Just out of interest Rich, what is the deal with these expensive plugs on the RM125? i sort of remember some ramplings from someone before, can these bikes accept standard BR9EG or ES plugs? i have a friend picking an RM up soon and i help him a bit with this sort of stuff and need to be aware of any problems.
I wonder if young Marcus here gets another KX125 next year if it will come with the expensive plug also, apparently a lot of engines got taken out by the plugs falling apart.
