Beautiful new aftermarket sidecover. Put right on if you have the white model, or pull out the heat gun, take the sticker off and repaint to the color you want. In Major Cities Sherwin Williams paint store can do a color match for yours and then even put the paint in a spray can so you can paint to match.
If you want a pair, I have the right one for sale under a separate sale.
These measure exactly up against a pair of Honda 1970 CB100 original sidecovers I have in stock. It will fit the left for a 1070-1972 CB100 and for 1973 to at least 1975 and probably later models.
It should also fit 1970-1973 CL100 just for left side.
Measurements top, across pin to pin on center 23.6 mm o.c.
top front to bottom pin17 mm o.c.
bottom pin to rear top 25.9 mm o.c.
I also have a picture that you can see the measurements.
Please check it or email me if you have questions.
