They said a four-cylinder motorcycle was impossible. Honda said, “Hold my sake.”
In the late 1960s, a certain Japanese manufacturer was tinkering away in its engineering labs. The idea was wild: a four‑cylinder engine, a front disc brake, smooth handling — and make it affordable?
That bold vision turned into the CB750, a bike that would kickstart the superbike era, democratize performance, and utterly reshape motorcycling forever.
How Many CB750s Were Made? The Numbers Nobody Can Fully Agree On
Below is what we know — or think we know about CB750 production numbers by year and model. The math gets fuzzy, people argue in forums, and a few engine numbers might’ve been etched on napkins. But the general consensus? Somewhere between 400,000 and 550,000 CB750s rolled off the line — depending on whether you count just the legendary SOHC models or include all the later variants.
🛠 CB750 Production Timeline by Model Batch
| Model / Variant | Years Produced | Estimated Units | Confidence Rating | Notes |

| CB750 F3 | 1978 | ~18,400 | ✅ High | Last SOHC F variant |
| CB750 A Hondamatic | 1976–1978 | ~8,100 (total) | ⚠️ Medium | Automatic transmission model |
| CB750 DOHC series | 1979–1982+ | Unknown (~50K+) | ❓ Low | Different engine design (not SOHC) |
| Total CB750s (1969–1978 SOHC) | — | ~400,000–430,000 | ✅ High | Confirmed production estimates |
| Grand Total CB750 (all variants) | 1969–1983 | ~550,000+ | ⚠️ Medium | Includes DOHC, Nighthawk, 750 Seven-Fifty |
Forum Feuds & VIN Madness
But — and this is a big “but” — not all of these numbers are universally agreed upon. The CB750 community is full of VIN sleuths, production-code purists, and engine-stamp truthers. Depending on who you ask:
-
VIN-tracking threads estimate only ~60,800 bikes between the initial sandcasts and the first mass batch.
-
Others argue records were inconsistently kept — especially in Honda’s early scramble to scale production.
-
Many frame and engine swaps over the decades further muddy the stats, especially for restorations.
A Little Story — The Wild Chronicles of the CB750 Production Line
Imagine a dimly-lit factory floor in 1968 Japan. Engineers huddle over blueprints, casting engines by hand, hoping their bet pays off. The first “sandcast” bikes — rough, raw, yet revolutionary — began quietly rolling off the line.
Then came the flood: magazines went crazy. Riders wanted in. Honda ramped up fast: from 25 to 100 bikes a day. Soon, they weren’t building a motorcycle — they were building a movement.
From the iconic K1’s 77,000 units to the disco-tinted F2s and the short-lived Hondamatics, each model carried forward a legacy that was becoming bigger than the sum of its parts.
Why the Uncertainty (And Why People Still Obsess)
-
No master list: Honda never published full annual production data.
-
Variant chaos: Do you count only SOHC models? What about the CB750F, A, or even the DOHC “Nighthawks”?
-
VIN gaps: Many original parts have been replaced, repainted, or re-frankensteined.
-
The legend effect: People inflate numbers and memories alike — because myths are more fun than math.
Final Thoughts — The CB750 Magic Lives in the Mystery
So, how many CB750s were made? Depends on who you ask. Some say ~400,000. Some insist it’s well over 550,000. Truth is — nobody knows for sure.
But here’s what we do know: the real magic of the CB750 isn’t in a spreadsheet. It’s in the fact that Honda dared to do what others wouldn’t. They made a four-cylinder performance bike for the everyday rider — and in doing so, changed motorcycling forever.
The CB750 wasn’t just a bike. It was a rebellion wrapped in metal — smooth, loud, and just unreliable enough to have a personality.
And that’s why it still roars in the hearts of riders, collectors, and dreamers today.
