Multiple speed record holder Mr Eisenberg, 46, said he was celebrating at Elvington Airfield near York after breaking the Federation Internationale de Motocyclisme (FIM) record for a flying kilometre on the bike his friend and colleague Daley Mathison was due to ride in the TT Zero race earlier this year.
‘I made a promise to him, and to his wife Natalie, that I would take the bike to world glory,’ said Mr Eisenberg. ‘He’s hopefully smiling down now from heaven.’
Mr Mathison died this year at the age of 27 in a Superbike event before he was due to race on the bike, which had been developed for him and his MADMAX team by engineers at Nottingham University.
The electric motorbike world had been waiting for a showdown between Mathison on the Nottingham University machine and the Mugen IOM TT bike built with the full resources of Honda.
As he recorded an average of 185.1mph for two runs over the flying kilo, Mr Eisenberg had a photo of his friend in his leathers and was wearing Mr Mathison’s knee slides.
‘He was with me on every ride,’ he said.
Mr Eisenberg also broke the FIM records for a flying quarter, a standing kilo and a standing quarter at the Straightliners Land Speed meeting, which is running over the weekend at Elvington. He said the bike achieved a top speed of 194.06mph as he performed a series of runs during the event on Saturday.
‘We all felt he was there with us.
‘A lot of bikes were struggling for speed today because of the wind, which makes what the team has achieved even more special.
He said any bike would have struggled to reach 194mph because of the wind.
‘It’s been an absolutely fantastic day. It was an absolutely amazing effort by the Nottingham University team. This is a completely British bike built by PhD students from Nottingham University. It’s a great achievement for British engineering.’
The Isle of Man TT Zero bike, which has been a TT podium winner for three years in a row, was developed by a team at Nottingham University led by Professor Miquel Gimeno Fabra. Mr Eisenberg continues to do Guernsey proud and now holds more than 50 world records on bikes and in cars.
