Great Oil
Using this oil in my RC8R. Just did second oil change and this oil was not burnt and still translucent. The clutch operates flawless and the oil is doing its job. It's a bit expensive but worth use in a nice bike.

Convenient Packaging
I am a BIG Fan of Fully Synthetic Motor Oils. I use them in all of my vehicles. You get less wear and longer life from Synthetics. I use Mobil 1 in my Automobiles and have not had any problems with the oil breaking down from my abuse or accidentally going 3000 miles past my scheduled oil changes. I haven't had the Power Synt 4T Synthetic in my bikes long enough to make a propper evaluation, yet.. But I have noticed that the bikes seem to be easier to start, now.

The 1 liter containers have a very convenient pour spout; Don't have to search for a funnel.

PROS: Easy Pour Containers, Fully Synthetic, Multi-grade

CONS: Expensive

BEST USES: Bumper To Bumper Traffic, Aggressive riding

Motorex 10-50
2008 ktm 530excr, tried every oil available and could not start bike in gear cold. Used factory recommended motorex and instantly had a great feeling clutch. Feels like new again and able to start bike from dead cold in first gear and bike will idle. Worth the money.

PROS: KTM, Clutch Oil

CONS: Price
