A man who was killed on a Mundford road last year was raising money for so people with incurable cancer could experience a motorbike track day.

Carl Bourne, 47, had been visiting Norfolk from his home in Cranbrook Drive, St Albans to take part in a group ride out, an inquest in Norwich heard this afternoon.

Leanne Ross, who with her partner organises motorcycle ride outs, was at the rear of the group travelling on the A134 in Mundford on September 11 last year.

In a statement given by Ms Ross and read by area coroner Yvonne Blake it said Mr Bourne, an industrial designer, had overtaken a number of vehicles safely, but as they approached the end of the road he put some distance between himself and Ms Ross.

It was thought Mr Bourne was travelling at between 80 and 90mph, and he overtook a car towing a caravan.

The speed limit on the stretch of road is 60mph.

Ms Ross lost sight of Mr Bourne, but when she positioned herself to overtake she saw his Suzuki go to the left, and then that he had come off his bike.

And although the driver of the car towing the caravan carried out CPR, Mr Bourne was pronounced dead at the scene.

Blood samples showed Mr Bourne had cannabinoids in his system, however Ms Blake said: 'They are very difficult to measure because they can increase in the blood after death.'

And therefore it was not possible to say how this could have affected Mr Bourne's ability to drive.

A crash investigation report from Norfolk Police concluded that Mr Bourne and his bike slid along the grass verge, before Mr Bourne came off the bike and collided with a lamppost.

It concluded the crash was likely due to 'the mix of excess speed and possibly diminished ability - this may have been exacerbated by the sudden change of lighting as he passed into the sunlight.'

The medical cause of death was given as excessive skull, neck and chest injuries as a result of a road traffic collision.

Before his death, Mr Bourne had been raising money through his own charity Incurable Global Tracktime.

He aimed to raise money to give those with incurable cancer the chance to have a go at a motorbike track day.

On a JustGiving page set up for the charity, Mr Bourne said: 'This matters to us because we are so passionate about motorcycling, and motorcycle safety in general.

'It is well documented how much a motorcycle rider's visual skills, motorcycle handling and an overall greater appreciation of both personal and the motorcycle's limits, improve with tracktime.

'And as passionate track riders ourselves, we want to empower as many fellow riders as we can experience this beautiful and life-affirming experience at least once.'

After Mr Bourne died, his brother Ivor continued to raise funds in his memory.

Ms Blake gave a determination that Mr Bourne died due to a road traffic collision.
