The 120/80-18 looks like the closest option even though by my calculations it would cut sidewall height by 8mm.

EDIT: Im dumb. I didn't even look at the V-rated version of the tire. They do have the 130/80-18 size in the V-rated version. I certainly don't need V-rated rubber on a W650 but it's only a couple bucks more to get the right size so I'll probably just do that.
I know on car tires the ratings do make a big difference in handling.

The higher the speed rating, generally the stiffer the sidewall, so better handling.

Probably the same for bike tires.
