I bought these rims for my last build

The original rims are 16 x 1.85. The rims above are 1.60 but you can't tell the difference,
There was one slight modification. The spoke holes had to be slightly reamed out. So if your have a reamer, or know a shop that does, these rims worked well for me.
Below is a pic of the bike with the Yamaha rims. This bike was a rusty white bike like yours.
