has anyone ever used maxima or motul oil in there bike if so with one and did you have good result?

my bike is an 08 xl1200 nightster

 

Never heard of them.

 

They are both good, Maxima is owned by a guy named Dick Lechien, if you followed motocross in the 80's you would have heard of his son Ron Lechien. Motul is a highly respected european oil company, the have been involved in racing for a very long time. I have used Maxima in the past, I have not used Motul but if it was better supported in the US, I would not hesitate to use it.
