My first 750 didn't have one.
My 2nd 750 has never been without it, not for 2 total miles. I am about to give it the 4th paint job for its next 'life'.
The difference: on my first 750, a long day's ride was 300-400 miles, an you were tired and your reflexes seriously impaired. On my second: back-to-back-to-back-to-back 1000 mile days were not enough riding, leaving me (and her) wanting more. My brother had a 'Jammer on his CB500-4, and we rode side-by-side (with the Lowers installed) for tens of thousands of miles together across the whole USA, summer after summer, 1000 mile days being normal, even when the speed limit was set at 55 MPH. We once rode 6780 miles together in 8 days, starting at Amarillo, taking in Carlsbad Caverns the next day, Grand Canyon the day after (for 2 days), then Phoenix, out to LV, across Utah to Colorado, toured this state to Denver. He stayed at my place overnight, hit the road back to Missouri the next day.
I have a collection of 750 Honda pins somewhere from those years (little vest, collar, or hat cloisonae pins), and 100% of them are depicted with 'Jammers on them. From 1970 through the end of the 750's dominance of motorcycle touring, a LARGE majority of the 750s had one. I would estimate more than 1/3 of the 500/550 bikes had them, and even many of the CB350 (twins) and 350F bikes sported them in the Midwest, before I moved to Colorado. Out here, they were even MORE common, with their lowers attached, on nearly every 750, 500/550, Kawi 900/1000, and Suzy triples and Fours I saw for years, even those from other states, touring out here.
While you couldn't throw a dead cat in the 1970s without it landing on a CB750, it would most likely end up lying on a side pocket of the 'Jammer when it landed.
