Just better oil all around, pick an aspect and it's better. I would imagine it then results in longer engine life as well as clutch and trans life since it is designed for that. The Mobil Racing 4T is comparable , I would run either one. I guess it all depends on what your bike is worth to you. If it isn't worth the extra money to run the best oil you can get then buy cheaper oil if it is worth it then buy the good stuff, it's your bike. My post was just my surprise at how much oil has gone up since last spring.

I learned all I need to know about life by killing smart people and eating their brains.
