A toddler's ecstatic reaction to motorcycle racing has been watched more than 40 million times after his father posted it to Facebook.
Two-year-old Logan Cox was taken to last weekend's MotoGP race at Silverstone Circuit in Northamptonshire by his parents, where they caught the 20-second-long clip of the youngster celebrating.
Wearing a t-shirt supporting Italian Yamaha racer Valentino Rossi, Logan is seen grinning, clapping his hands and laughing as he watches the high-powered motorcycles race around the track.
More than 227,000 people have commented on the video, while a further 434,000 have liked it.
Speaking to the Daily Mail, Logan's father Daniel Cox said: 'We stood in a place where all the bikes were coming down and at that point were shutting off so they were banging as they were shutting off.
"He loved the bikes doing that and every time his reaction was the same, his reaction was brilliant."
He added: "I thought a few people might like it but I didn't expect it to get this big this quick."
Following the video going viral, the young motorcycle fanatic has been invited to next Sunday's British Superbikes event at Donington Park where he will be allowed to sit on the bikes.
