Chris Adams ' heartbroken brother said the Erskine father-of-one had been enjoying a great day out at the track when the tragedy unfolded and he was thrown to the ground.

Now Chris' devastated family is coming to terms with their loss as friends rally to raise money to support his young son.
Brother Blair, 33, said: "When I first got the news I thought Chris must have just slipped off his bike and broken some bones. I could never have imagined how serious it was.
"When I arrived at the hospital with my mum and dad he was already on life support. We all sat at his bedside for two days. It was my mum's 70th birthday that weekend. It was horrible and we just waited.
"The doctors did as much as they could, but he never woke up. Then we decided that Chris' life support would be turned off. There was nothing more they could do."
Chris had been on track days many times at Knockhill and was also due to go on a trip to a circuit in Portugal later this year. He was well-known and loved across the motorbike scene and also had his own dealership business, CA Motorcycles, in Glasgow.
Blair said: "We all grew up loving our bikes. My dad had them too. The sport has been very much part of the family.
"I now have a lot of friends saying they are not going on a bike again after what has happened to Chris, but I don't think he would want that. Up until the moment he came off his bike, he would have had a smile on his face."
Friends across the motoring industry have since donated thousands of pounds for Chris's young son. Blair added. "We're speechless at the amount of support people have shown. There have been donations from all over the world. This is a very hard time for our family but one thing we know is that Chris would want his son to have the best possible future."
