You can use any 15/40 HEDO in your bike. My only question would be, since Rotella can be bought so cheap and they go through the effort for JASO why bother with other brands?
I guess for the same reason I have used all the HEDOs in my metric bikes!
I THINK, if I remember correctly I liked the way my shifting lasted with Delvac 15/40.
I have also used Delo 15/40, Valvoline 15/40 and of course Rotella.
But honestly, my favorite was convnetional 20/50 Valvoline 4 stroke motorcycle oil, nice grabby feeling in the clutch, $4.00 a quart in the bigger walmarts.
