NO CAR /LORRY OIL ISNT GOOD FOR BIKES!!!!! there made differnt car lorry oils have additives that will give you clutch slip ,as the oil is not made for a wet clutch ,it does not like gear box thrashing and is not up to the job of protecting at 13,000 rpm .I used in a bike i had and it did it no good at all .I know motorcycle oil is expencive but please if you love your bike use the right oils.
