I'm interested in what synthetic oil some of you may be using in your KTM EXC models? KTM recommends using the Motorex Power Synt 10w/50 for the 2009 450. Is anyone trying other brands? Spunkys is charging $22.99/litre for the Motorex. The oil is meet JASO MA specs. I was looking into the Amsoil 20w/50 synthetic which has this JASO MA-MA2 standard. It also ranks #1 out of all the motorcycle synthetc oils. I can also get it for about $11-12.00/litre.![]()
