In brief, the 1976 Honda CB750 family could reach roughly 110–125 mph (177–201 km/h) under ideal conditions, with many sources citing about 120 mph as a typical figure.
The question involves several CB750 variants produced in 1976 and how performance varied by engine tuning, transmission, aerodynamics, and testing conditions. Here is a concise look at typical top speeds for the main 1976 models.
Variants and their top speeds
The speeds below are representative figures drawn from manufacturer data and period road tests; actual performance can vary with aerodynamics, rider weight, tire choice, and altitude.
- CB750K (Standard, manual transmission) — approximately 110–125 mph (177–201 km/h) in optimal conditions.
- CB750F (Super Sport, manual) — around 120–125 mph (193–201 km/h), reflecting sport-tuned tires and exhaust.
- CB750A Ascot (automatic transmission) — typically about 100–110 mph (161–177 km/h).
Conclusion: The 1976 CB750 lineup generally delivered top speeds in the neighborhood of 110–125 mph, with the automatic Ascot trailing a bit behind the manual models due to drivetrain losses and gearing.
Measurement notes
Top speed figures are highly dependent on testing methods, whether the motorcycle is equipped with the stock fairing, rider position, and wind conditions. Most published numbers come from controlled tests or rider-tuned highway runs rather than informal street riding.
Summary
The 1976 Honda CB750 family typically reached around 110–125 mph (177–201 km/h) depending on the variant and conditions, with the standard and sport models at the higher end and the Ascot auto variant slightly lower. These speeds place the CB750 among the era’s notable sport-tourers.
