I don't see the point in using 300v for street use.
that is True, 10x
I recommend Motul 7100 10w60 in hot condition +- 30 - 45c
I install on my bike oil pressure gauge and I am looking always there what pressure I have when I am driving...so the best valve was when I put there 10W60 Motul 7100,
7100 It's high quality oil, 5100 medium quality oil,
I want to told you all that I am always using oil additives, - Bardahl Full metal.
P.S. I am owner Kawasaki zx10r 2011 and this is my 8 bike in my life, I have stunt bike too Kawasaki zx636r 2004 B1, so I suggest you all that never use 300v Oil when you are riding on street or street ricing, this oil is very thin and when you driving in street you can't put in your hands always high RPM, this means that thin oil always going very fast down and you have low oil in engine when you have low pressure at low rpm, this oil is good when you are driving 90 % in high rpm(up to 8500rpm) and this oil is for onetime use only...+ if you will use this oil soon your clutch and your engine will have low resource.
you must Know where,what,how and why to use,
I made test about additive and all oil what we have in our life, Motul,Castrol, Mobil 1, Shell, nobody use normal additives in oil because you will have high resource and your engine never will stop working, and this will be bad for company Kawasaki, BMW, Mercedes, because they have contracts, there service will not work normal...All company what to make like this oil that 100 000 km engine start to work bad, (about cars)
So, I recommend if someone don't believe this go and buy Badrahl Full metal Additive for motorcycle and make own tests, I promise you that all you will be happy. ))
Benefits: low friction, low temperature, fast rpm up and down, normal oil PSI pressure (manual recommendations: +-28PSI at 5000RPM at 50c temp.)
If you don't want to use any additives, use Motul 7100 10W60 IF YOU DON'T DRIVING ON WINTER. (-10C) if you drive on winter use 10w50, don't use 5100 motul, and if you drive only on winter use 10W40 7100.
thanks for attention,
