World-famous motorcycle racer Guy Martin's attempt to break the two-wheel land speed record has suffered yet another setback when his 400mph bike toppled during a test run.

The 34-year-old was attempting to reach speeds of 300mph during the trial, a requirement before he attempts to break the record, when his bike slipped on a damp patch on the Bonneville Salt Flats in Utah, USA.

This is the the latest incident to hinder the record-breaking attempt, which currently stands at 376.36mph.

Just days ago the 400mph Triumph Infor Rocket Streamliner was damaged as it was being towed into position on the start line.

The Isle Of Man TT star escaped the incident uninjured, although the 1,000 horsepower bike will undergo a full inspection before any further attempts can be made.

During practice sessions over the Summer, the bike became the fastest to be built by Triumph as Guy achieved a speed of 274.2mph. The bike is 25.5ft long, 2ft wide and 3ft tall with a 1,000 brake horsepower, producing 9,000 revs per minute.

The East Yorkshire-born driver is experienced in setting speed records which includes fastest speed on a gravity-powered snow sled, in a soap box and highest speed around a wall of death.
