These are Wald #8095. They call them touring bars but they're North Roads for sure. Steel but not very heavy. They measure 23" wide. I think the Nitto's measure about 21" or 22" like the original Brit bars. The wider, the better for handling. The Wald's will set you back about $15, so if you don't like them, you're not out much.

The stem is a cheap adjustable with about a 70mm extension. This puts the middle of the grips about center with the stem bolt. No handling issues even when the bike is fully loaded.
