  Despite his injuries it has been reported that Martin has already signed himself out of hospital in Belfast.
  A spokesman for Triumph said Martin was "central" to their record attempt.
  The TT racer and television personality from Grimsby, Lincolnshire, is planning to beat the current 376.363mph record (605km/h) in Triumph's 1,000 bhp Rocket III Streamliner.
  A spokesman for Leicestershire-based Triumph said: "Guy is a unique talent and having such a pilot is absolutely central to our attempt.
  "We wish him a full and speedy recovery and will confirm a new date for our 2016 bid as soon as we can."
  On Monday, Martin tweeted: "I'm on the mend - few upgrades to me hand& back but feel right enough. All part of the job. Thanks very much for the support as always."
  He is reported to have fractured a vertebrae, his sternum, and a number of ribs in the 100mph crash as well as damaging his throttle hand.
