Small XR models include the XR50R, XR70R, XR75R, XR80R and XR100R. They are much smaller in size in comparison to the other bikes in the series, and are designed for children, smaller riders, as pit bikes, or for recreational fun. The young John Connor rides an XR80 in Terminator 2: Judgement Day, while his stunt double uses the XR100 for his shots of the film.
The XR 50 is a small four-stroke 50 cc (3.1 cu in) child's entry level motorcycle, produced from 1969 until today. Originally it was called the Z-50, then Trail-50, the XR 50, CRF 50, and the mini motard XR 50. This model is not sold in the United States due to the CPSIA.
