One of the best oils around.
A true Group 5 ester based synthetic, this is the real deal and compatible with your wet clutches. I have heard there is a little PAO in there but that is Group 4 still. Much Much better than that crap they call synthetic in the U.S. I'm looking at you Castrol with your Group III base oil, you've even convinced Mobil and most other "synthetic" oils to go mainly group 3 with your cheapness. I used this in my Honda 250EX and the shifting is sooo much smoother when not using the clutch compared to the oil I was using which was the Valvoline "Synthetic" motorcycle that is mainly Group III oil. This only costs about 6 more dollars a quart and is worth it considering you can do a long drain interval if you really want to but to pay only 6 more bucks and get the best up there with Motul I'm sold. I support Redline being a U.S. company.
