MORGANTOWN, W.Va. – MX Sports Pro Racing has confirmed that 20-year-old AMA Pro Motocross racer Jonathan Mayzak has died.

Mayzak died Sunday as a result of injuries sustained Friday night before the Unadilla National in New Berlin, N.Y., when he was struck by a vehicle while crossing the road in front of the paddock on Route 8.

State Police have charged the 31-year-old man who was operating the vehicle with driving while drug-impaired and vehicular assault.  More charges are expected as a result of Mayzak’s death.

Mayzak first competed on a national stage in 2006 when he earned a gate at the 2006 AMA Amateur National Motocross Championship at Loretta Lynn’s in the 51cc (4-6) Class, and again in 2015 in Open Pro Sport.  In 2016 Mayzak earned his professional motocross license and was assigned No. 210.  This year the No. 210 competed in the Lucas Oil Pro Motocross Championship in four events in the 250 Class, including the inaugural Florida National and historic Southwick National, making the Fast 40 in both.

Mayzak and his fiancé, Kenzie Hebbelman, were planning to marry in October and take a cruise for their honeymoon. In addition to Kenzie, Mayzak is survived by his parents and several siblings, two of which are in the military serving our country.

Services have not yet been announced.
