The 1976 Honda 750 lineup produced roughly 60–67 horsepower, depending on model and how the power was measured.
In 1976, Honda offered several 750cc variants built on the same inline-four platform. The differences were largely in transmission and tuning, which affected published horsepower figures and real-world performance.
Horsepower by 1976 Honda 750 variants
Below is a breakdown of the most common 1976 CB750 models and their typical horsepower ratings. The values reflect period specifications (gross engine output) and note variations based on testing standards.
- CB750 Standard (base CB750 / K-series): about 67 horsepower (gross) at around 8,000 rpm; net horsepower at the rear wheel would typically be in the 50–60 hp range depending on condition and measurement method.
- CB750F Super Sport: around 67–70 horsepower (gross) as marketed in the mid-1970s, with peak output at higher rpm (roughly 8,000–9,000 rpm).
- CB750A Hondamatic: roughly 58–60 horsepower (gross) due to automatic transmission drivetrain losses; real-world rear-wheel output would be lower still.
These figures illustrate the general ballpark for 1976 750cc Hondas. For a given bike, the exact horsepower depends on the model's tuning, cam timing, compression, exhaust, and whether the rating is gross or net.
Notes on horsepower ratings
Horsepower ratings from the era were typically published as gross engine output (before drivetrain losses). Modern references may quote net figures or rear-wheel horsepower as measured on a dyno, which are usually lower due to exhaust, gearing, and transmission losses.
Why the models differ
The CB750 line shared a common 748cc inline-four, but Honda tuned and marketed variants differently. The Hondamatic's auto transmission introduced a drivetrain penalty, and the F Super Sport model emphasized higher revs and sportier cams to extract extra horsepower in the upper RPM range.
Summary
In short, the 1976 Honda 750 family produced roughly 60–67 horsepower across variants, with the base CB750 and CB750F delivering around 67 hp gross, and the Hondamatic version slightly lower due to drivetrain losses. If you’re restoring one or evaluating a used bike, a dyno test or a look at the factory service bulletins for your exact frame and year will give the most accurate figure for that specific motorcycle.
