A TEENAGE motorcyclist died after losing control of his vehicle and crashing into a brick wall, an inquest heard.

Ryan Leech died at Wexham Park Hospital on Friday, August 30 as a result of serious chest injuries he sustained in the crash on Hedsor Road, Bourne End.

But the inquest into the death of the 19-year-old former Great Marlow School pupil, of Booker Place, High Wycombe, heard that although concerns about the condition of the road surface were raised, it was impossible to determine why he lost control.

Collision investigator Andrew Evans described the surface of Hedsor Road as "uneven, undulating, with numerous repair patches".

Coroner Richard Hulett asked if there was anything of note at the scene that could be linked to the cause of the accident. Mr Evans replied said there were marks in the road 25 metres prior to the collision scene which indicated slipped tyres.

He said: "There's a tyre mark - when cars go round corners too fast and it slips it leaves a mark. I have personally never seen a motorcycle tyre do that, but it's there. There may be an unusual set of circumstances caused by a weaving bike but I can't particularly link it to the motorcycle.

"It's entirely feasible the motorcycle had slipped sideways prior to impact causing these marks, though it could have been made by another vehicle not connected with this collision."

A police reconstruction showed machine fitter Mr Leech was travelling at around 40mph along the road, which Mr Evans did not believe to be excessive.

He said travelling at that speed "worked the suspension" during the test, but he added: "At no time did it cause it to wobble, weave or lose stability."

Mr Evans said there was no evidence of emergency braking. Post mortem tests also showed Mr Leech was not intoxicated at the time of the accident.

Mr Leech's stepdad David Newman said he had had his black Yamaha bike for around a year and was riding to Slough to see his girlfriend when the accident happened.

Mr Newman said: "At a fairly young age, around six years old, he had been riding bikes in farmer's fields. He'd always had a knowledge of bikes and riding."

He added: "I think there's a gap in the unknown within that split second. There's only one person who knows what happened on that day."

Mr Hulett recorded a verdict of death by road traffic accident.
