However it was not until 1922 that the first time the Lightweight TT took place, won by motorcycle journalist Geoff S. Davison riding a Levis, at an average speed of 49.89 mph (80.29 km/h) for 5 laps of the Snaefell Mountain Course.

In the changes following the loss of FIM World Championship status after the 1976 event, the Lightweight TT event was dropped with the 250 cc machines running for the Junior TT in place of the now defunct 350 cc formula.

The Lightweight TT returned in 1995 before being split into two distinct events from 1999, dropping from the schedule again after 2004.

The event was re-introduced for the 2012 races on the Mountain course, with a change to water-cooled four-stroke twin cylinder engines not exceeding 650 cc and complying with the ACU Standing Regulations.

The lap record for the Lightweight TT is held by Michael Dunlop in a time of 18 minutes and 26.543 seconds, at an average speed of 122.750 mph (197.547 km/h) set during the 2018 race.
