Two teenage motocross riders have been flown to hospital following separate crashes in the Illawarra and Shoalhaven on Monday.
A 15-year-old boy sustained fractured limbs after crashing mid-race at the Wollongong Motorcycle Club's track at Kembla Heights about 12.15pm.
NSW Ambulance Illawarra duty operations manager Inspector Matt Sterling said the rider came off his bike going over a five-metre jump.
It is believed he was travelling about 50km/h at the time.
Insp Sterling said the boy did not lose consciousness, but did sustain fractures to his leg and wrist.

Meanwhile, another rider was injured at the Nowra MotoPlex in Yerriyong on Monday.
