“A vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control.” - American National Standards Institute
ATV riding didn’t start out as a sport necessarily. It was originally used by farmers and landowners for work. Many people eventually discovered that riding ATVs are so much fun. Thus recreational ATV riding was born. So, yes, recreational ATV riding is most definitely now a sport.
Recreational ATV riding is exactly what it sounds like, it is riding either a 4-wheeled motorbike or a side by side for the purposes of sport and recreation.
