They were affectionately called
Snortin' Norton
By the late 1960s
competition from Japanese manufacturers
drove the whole British motorcycle industry into decline
The 750 Norton Atlas was noted for its vibration
Rather than change engines
Norton decided to change the frame,
and the isolastic-framed Norton Commando 750 was the result
In 1969, the Commando was introduced
Highlighting its styling, frame and powerful engine
65 bhp @ 6,500 rpm
The Commando was the most powerful and best-handling British motorcycle of its day
The "Combat" engine was released in January 1972,
with a
twin roller bearing crank,
crank-shaft main-bearing reliability immediately suffered
crank-bending caused the rollers to "dig-in" to the races,
causing rapid failure
Older engines had used one ball-bearing main bearing
and one roller bearing main bearing
Electric start was introduced in 1974
Sales were respectable but the company declined financially
becoming insolvent in 1975
