Mobil 1 Racing4T is lablled 15/50 and sold here in Oz as a motorcycle oil. I've use dit foe years in my road bikes as I have had access to Mobil at wholesale prices. Mobil 1 generally has a good reputation, and I still use the 5/50 in my car and ute.
Subjectively, the Racing 4T does seem to pour a easier out of the bottle in winter compared to the Delo 400 even though they are both rated 15 w
