In July 2015 it was confirmed that Martin was to pilot Triumph Motorcycles' attempt on the motorcycle land speed record (World’s Fastest Motorcycle), at the time standing at 376.363 mph (605 km/h), set by Rocky Robinson in 2010.The attempt was originally scheduled for August during the FIM event at Bonneville Salt Flats in the United States.His first job after leaving school was as a heavy vehicle mechanic, which he retained since, being unwilling to give it up for full-time racing and media.His father Ian was a successful privateer motorbike racer who had competed in several Isle of Man TT events, but he was forced to supplement his income with a job as a lorry mechanic, additionally selling bikes.Despite enjoying the work, due to the amount of time it was taking to film his Speed series, time taken away from his maintenance job, Martin considered taking a break from television in 2015.He changed his mind after reaching a deal to film the India and wall of death programmes, and possibly a few more one-off Speed specials, including an unstated record in Europe.
The end of 2009 saw Martin leave Hydrex for Northern Ireland-based Wilson Craig Honda, but since November 2010, Martin has raced for TAS Racing (known as Relentless Suzuki, then Tyco Suzuki from 2012 to 2014, and Tyco BMW from 2015 to present), the team run by the Neill family also based in Northern Ireland, and with a long TT heritage.
Martin returned to the Isle of Man at age 16; overhearing lorry driver and amateur racer Baz Kirk discussing his plans to race in the 1997 Manx Grand Prix with his father, he was offered the chance to assist him as a race mechanic. In 2004 he moved to the Uel Duncan Racing team, staying with them until 2005.
In 2006 Martin raced for Alistair Flanagan's AIM Yamaha race team, replacing John Mc Guinness.
Although his interest matched his father's trade, he was happy for Guy to do his own thing, and indeed would try to stop him "talking the whole time about engines" during family holidays to Butlins.
Martin attended Kirmington Church of England Primary School and The Vale Academy school, leaving at age 16.
