Not totally certain what it came off of. So it isn't a guaranteed fit for a CB CL350. However, t looks very similar to a CL CB 350 crash bar I had sold previously.
It is 27 inches wide 14 3/4" inches tall and includes 3 mounting U bolts. I I believe the key measurement is the engine bolt distance at the bottom mount which must be smaller than 8" across which is its current inside diameter.
Chrome is very good except for an approximately 3 inch scrape on its side which is shown on the pictures.
PLease email me any questions about fitment, as parts are not returnable.
