hello, Amsoil offers two kinds of oil. The one I have used is just called synthetic motorcycle oil in 10w-40 weight and it is 6.35 a quart my cost. The other is a new kind called high performance in the same weight and it is 8.05 a quart. kinda high, thats the reason I don't use it anymore. If you don't ride a lot of miles in a year this is what I would go for. They also offer there super duty motorcycle oil filters that are designed to be used along with their oil. I have used them in the past with no complaints. The part number is SMF-109 and they are 9.40 each. Let me know, if you want any of this or need more help.
