After numerous retirements in 1924, Wal Handley won the Junior TT race over six laps of the Mountain Course on a Rex-Acme motorcycle at an average speed of 65.02mi/h. Later in the week, Handley became the first TT rider to win two races in a week when he won the four-lap Ultra-Lightweight TT race, again on a Rex-Acme, setting a race record average speed of 53.45mi/h, and a new lap record of 41 minutes, 52 seconds at an average speed of 54.12mi/h.
During the Lightweight TT race, Wal Handley led the first two laps by over two minutes from C. W. "Paddy" Johnston, riding a Cotton, but a puncture caused Handley to slip off his motorcycle at Signpost Corner. The race was eventually won by Eddie Twemlow on a New Imperial at an average speed of 57.74mi/h from Johnston and Eddie's brother, Ken Twemlow, riding a New Imperial. The Senior TT race was sensationally won by Howard Davis while competing against the works teams with a motorcycle of his own manufacture, an HRD, in 3 hours, 25 minutes, 8 seconds at an average speed of 66.13mi/h. A new lap record was posted by Jimmie Simpson, in 32 minutes and 50 seconds and an average speed of 68.97mi/h on an AJS motorcycle, but he failed to finish.
