Making the worlds most extreme vehicles

Self-proclaimed Speed freak Zef, was the founder of Maximuscle nutrition products, but it was evident that speed was an obsession. Forming the Guernsey-based Madmax race team in 2011, Zef and his team worked with the best engineers and scientists to develop some of the worlds most extreme vehicles. Taking multiple world speed records with Motorbikes, cars, quads and other land vehicles. Just from a motorcycle point of view, the records are unbelievable including the fastest naked motorbike.

Eisenberg racing, builds bespoke high-speed cars and bikes, particularly the Eisenberg V8. Working with Prodrive the two created a limited production run of a 480hp V8 motorcycle, considered the most powerful production motorcycle, seeing 225mph top speed and a 10,500 rpm rev limit. The launch was hoped for 2021 with a cost of around £160,000.

TT Zero, University of Nottingham

Not content with just tuning combustion engines, Zef and his team re-engineered the IOM TT zero entry from the University of Nottingham to settle some unfinished business. The double heartbreaking story that saw Daley Mathison killed the day before the IOM TT Zero race at TT 2019, never getting chance to race the updated project for that year which was hotly anticipated to take the top spot on the podium. Zef promised Daley’s wife Natalie, that the Nottingham bike would be taken to world record glory.

Re-engineering and making the bike even more powerful, Eisenberg smashed four FIM world speed records, on the bike, whilst wearing Daley’s trademark Daisy knee sliders.

Away from speed, Zef was a highly successful businessman forming Sports nutrition company Maximuscle which changed the game. Being the first UK company to have its products screened to WADA (World Anti-Doping Agency) rules, it had a huge range of nutritional products aimed at active people.
