Sorry if this question has been done to death, but I am far too old to understand the mechanics of forums! Anyway I due to all the positivity regarding Brisk plugs, I would like to put on in my ,2011 Sym 300 gts evo. There does seem that I can find some suggesting the AO12 and others the AOR14. Any advice appreciated.

if you know and post here, the NGK plug you are using now, then i will be easy to advise which you require cheers

If it's the 263cc efi engine (great engine BTW) then it's a CR8E with a gap of 0.6-0.7mm.
