The 1922 Isle of Man Tourist Trophy introduced a new race, within a race, for 250 cc motorcycles called the Lightweight TT, to be run concurrently with the already-established Junior 350 cc that took place on Tuesday 30 May, and Senior 500 cc race on Thursday 1 June.

The new third race was achieved by splitting the 250 cc machines away from, but run simultaneously with, the 350 cc machines that had previously been racing together in the up-to-350 cc engine-capacity limit. Thirty three lightweights started first before the 350 cc machines,^[1] and the fastest lap was achieved by Wal Handley on an OK-Supreme at 51 mph (82 km/h). The win by Geoff S Davison on a Levis was the last TT win for a British two-stroke motorcycle.^[2]

By winning the 350 cc race, Tom Sheard became the first Manxman to win a Tourist Trophy race, with an average speed of 54.75 mph (88.11 km/h), covering 188.75 miles (303.76 km).^[3] Seventeen-year-old Stanley Woods attained fifth position on a Cotton with a time of 3hrs 50min 33secs, despite having to contend with a broken exhaust pipe and a pit-fire that set both man and machine ablaze.^[4]

Walter Brandish, placed second in the 500 cc race would become, in 1923, the first rider to have a bend on the course named after him (Brandish Corner). He just failed – by 22 seconds – to break the four-hour time that the winner Alec Bennett achieved for the first time in a six-lap race that he led from start to finish, with a new lap record of 59.99 mph (96.54 km/h).^[5] This was the last TT win by a side-valve machine.^[6]

It was held on Tuesday, May 30, 1922 at 10:00 am over a distance of 188.75  miles, 5 laps of 37.75 miles each. Lightweight machines were limited of cylinder capacity not exceeding 250cc., they ran concurrently with Junior TT machines of 350cc. Riders started off at intervals of half-a-minute. All 32 entries started the race in Lightweight class and 14 finished. Out of 37 entries in Junior, 35 started and 16 finished.^[7]
