Wolfman Explorer Lite Tank Bag.
Good stuff, USA made.
Pulled it off my KLR650,
used their 'universal tank bag' strap kit.
It's a little big on the Hyper, but fits well enough.
They make a few different tank bags.
I think the "enduro" model might fit nicer.
9.75 x 5.5" vs 11 x 8.75"

I had to get creative to mount the rear straps,
looped around subframe.
(Trying to avoid looping around frame tubes. Don't want to chafe that pretty red paint.)
It intrudes on the frontal saddle area, but only a little bit.
Not noticed with regular riding.
If I ever take this bike to the track, the bag would obviously come off.
the front straps were easy, looped around radiator mount tabs
