Nice, good report, just as good and better then many fine motorcycle oils. Yet the cost is much lower. I look at the Quicksilver as the Rotella of the Motorcycle Synthetic oils.
The viscosity is a bit lower in the 20/50 range such as HD360, Mobile 1 etc. But that is mostly known now and if you think about it, what does it matter, its still way more "heavy" then a 10 or 15/40 which is still good in any engine. Im in a super hot summer climate so I tend to look at that, not that it means anything. )
I feel for the price, if you want a syn specific syn motorcycle oil that you cant go wrong.
As Robinson said, if you dont go with a specific motorcycle oil, the Vr1 oils do turn in great numbers as far as UOAs. If what a UOA is all that matters to you.
