does the wr426f run on premium gas?????????????????

need to know if the wr426f runs on premium gas. i know my yz426f did and they are pretty much the same motor so i assume it does?

I run premium in all my bikes.

Recommended, however, in the event of an emergency/scarcity 87 will work just fine.

12.5:1 compression = hell yes!

91 octane is plenty good enough.
