Isn't that the racing oil? Would it be bad for motorcycles with cats?
AFAIK, Motul makes no claims about it being safe for cat equipped bikes. My bikes that I have used it in don't have cats.
And if you don't burn a lot of oil it makes no difference how much ZDDP the oil has. It only hurts the cat if you use a lot of oil and even then it just shorten's the life of the cat, it doesen't kill it over night. I've used high ZDDP oils in all my bikes(cat or no cat) and my S2000, both my Goldwing and S2000 have over 100k miles and the cats are working just fine because neither use much if any oil.
