IMHO these were at least mid 60s in Europe.
In 40s and 50s don't think even racing bikes had disc brakes, however its development goes back to around 1900..
First in vehicles, way before bikes.
Most likely the Italian Lambretta was one of the first using discs...around early 60s, followed by MV Augusta and Honda.

PB I believe the Norton Manx was produced from 1947-1962

Agree with the above but not with disc brakes in 40s-50s...I am talking about disc brakes, not bike/Manx.

Well that particular bike is a 61 350cc Manx that belonged to Eddie Byers who ( according to google) was a club racer in the early 2000's and was killed at the Isle of Mann in 2005 hence the disc front brake

Btw that particular bike sold at Bonham's auction for $ 25,517

The first disc brakes were on air planes.

OK, glad we solved this issue without bowing ...in which U R the master.

I am wondering if the front wheel on the above Manx image was an upgrade assembly that included a disc brake.

I think even early [production] 1970s Nortons (like the Commando) had the "advanced" ventilated front drum brake.

... I think, but not completely sure.

A great racer from England , Peter Williams whom recently died was one of the first if not THE first to use a disc brake on his bikes .

@GO - most likely you are correct.
The first motorcycle with a front disc brake operated by a cable, not hydraulics, I saw and tested in early/mid 70s, I guess??

@Houtman - many great racers and racing bikes from England....

I'm fascinated by the market positioning and mechanical execution of the Trident 660. 417 lbs. / 189 kg, 81 horsepower, & 47 lb-ft of torque in a compact bike with a round headlight for USD $8k is compelling.

I'm like LongRanger, though, not the biggest fan of some styling cues. Pain points are the stubby tail and the featureless black wheels. The stubby could be somewhat mitigated with a luggage rack and some Hepco & Becker C-Bow panniers, but the black wheels make even a light bike look heavier...there's too much visual weight down below. The wheels should look like wings, not boots.
