TT Zero
TT Zero – an electric motorsport event new for the 2010 Isle of Man TT races – replaced the TTXGP race as a 1-lap circuit of the Snaefell Mountain Course. The TT Zero event as an officially sanctioned Isle of Man TT race is for racing motorcycles where "The technical concept is for motorcycles to be powered without the use of carbon based fuels and have zero toxic/noxious emissions." The Isle of Man Government offered a prize of £10,000 for the first entrant to exceed the prestigious 100 mph average speed around the Mountain Course.
The inaugural 2010 TT Zero race was won by Mark Miller riding a MotoCzysz E1pc motor-cycle in 23 minutes and 22.89 seconds at an average race speed of 96.820 mph for 1 lap of the Mountain Course and the first United States winner since Dave Roper won the 1984 Historic TT riding a 500cc Matchless. The TT Zero race replaced the 2009 TTXGP franchise, won by Rob Barber riding a Team AGNI motor-cycle in 25 minutes and 53.5 seconds at an average race speed of 87.434 mph for 1 lap, with the simplification of the regulations and the emphasis on electric powered motor-cycles. The MotoCzysz E1pc was also the first American manufactured motor-cycle to win an Isle of Man TT Race since Oliver Godfrey won the 1911 Senior TT with an Indian V-Twin motor-cycle. The 2010 TT Zero race also produced the return of semi-dustbin fairing permissible under the TT Zero regulations and adopted by some entrants, but banned by the FIM since 1958 for racing motor-cycles.
After taking their first victory in 2014 Team Mugen from Japan have been the dominant force winning the event for 6 consecutive years from 2014-2019 and raising the average lap speed to 121.9mph
