i had my 76 550f osha saftey yellow for many years, and frankly i always loved it in yellow. It's a sorta metal flake graphite
now, and although it looks more... maybe stately(?), the yellow thing always seemed more playful and sporty (not to mention
visible!) The last yellow
combo was yellow tank with black side-cover and tank hatch with chromey-rubber edge trim on the tank.
i also bondo'd in the tank badge mounts many years ago, and have always dug the minimalism there.
The only side effect of a yellow bike that i've noted, is that "ride yellow" never sounds as cool as "ride red"
