It might be the shortest event during the TT fortnight, but the TT Zero packs the more technology and development than the other TT races combined. Every year, the electric race bikes make leaps of progress in their pace, and for 2015 the unofficial mark to beat was the 120 mph barrier.

Team Mugen seemed close to that mark during the practice sessions, with John McGuinness posting a timed 118 mph lap. With Bruce Anstey already a race winner from the Superbike TT, and McPint always looking good on the Shinden race bike, the duo was heavily favored to win.

This year’s TT Zero also sees the return of Brammo to the Isle of Man, disguised as the Victory Racing team.

Victory was originally slotted to have Lee Johnston and William Dunlop as its riders, but Dunlop’s crash during the Superstock race meant his TT racing was over for this year. Luckily, his Tyco BMW teammate, Guy Martin, was available and keen to ride the electrics, and thus substituted for the injured Dunlop.

Other entries include Saroléa and Saietta, as well as the university teams from Brunel, Kingston, and Nottingham.
