The Lightweight TT is a motorcycle road race that is a part of the Isle of Man TT festival - an annual motorcycle event traditionally held over the last week of May and first week of June. History1922 was the first time the Lightweight TT race took place, won by Geoff S. Davison riding a Levis, at an average speed of 49.89 mph (80.29 km/h) for 7 laps of the Snaefell Mountain Course. Between 1949 and 1976, the Lightweight race was part of the Grand Prix motorcycle racing season. The event was dropped from the 2005 race calendar due to lack of entries. The Lightweight TT and the Ultra-Lightweight TT were later reinstated to the 2008 & 2009 race schedules, but were held on the 4.25 mile Billown Circuit in the south of the Isle of Man.[1] For the 2010 races, the Lightweight TT was again dropped from the race schedule on cost grounds. 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.[2] The Lightweight categoryThere have been several different categories of motorcycle that can compete in this event. In the 1950s and 1960s, the principal TT solo events were the Senior (500 cc), Junior (350 cc), and Lightweight (250 cc, or sometimes 125 cc). The 125 cc class was occasionally called "Ultra-Lightweight". Currently the Lightweight class comprises road-based "Super-Twin" solo machines with liquid-cooled four-stroke engines of up to 650 cc engine capacity. EligibilityEntrants
