I have been using Amsoil for years during my GNCC off road race seasons without an oil related failure. This year I'm running 10w 40w oil designed for dirt bikes. Four races into the season and no problems and clutch wear has been minimal. VEry good product
I use the 10w 50 synthetic dirt bike oil in my KTM 350 SXF race bike. I have a rekluse clutch and with this oil, I can start the bike in second gear. With oils that I've used in the past, I was not able to start the bike in gear. In addition, I have a full season of two-hour woods endurance races on this engine with no sign of wear at all. I have friends with the same bike that use competitors oil that have already needed to rebuild both top and bottom ends. In my opinion, Amsoil 10W-50 dirt bike oil is the absolute best on the market!
Bottom Line
Yes, I would recommend this to a friend.

You have won my trust. Amsoil products are my default. I maintain my rigs, but run them hard. Sold my last truck at 275000 miles,wish I had kept it!
