A Brooklyn EMT was killed Thursday when her motorcycle burst into flames after she struck a double-parked truck in Brooklyn, police said.

Christina Gardini, 27, was going northbound on Bay 35th Street in Gravesend when she slammed into the unoccupied truck, causing her bike to catch fire around 11:30 a.m., cops said.

Gardini, who lived about two blocks from the site of the fiery crash, suffered severe burns, police said.

Photos of the scene show the charred remains of Gardini’s black bike left sitting behind the truck.

“She was a beautiful girl,” Gardini’s cousin, who asked not to be identified, told The Post. “She just got everything in her life together. We’re all devastated.”

According to her Facebook page, Gardini worked for Maimonides Medical Center.

A photo of Gardini on the social media site shows her smiling while sitting atop a motorcycle, which appears to be a different bike from the one involved in Thursday’s crash.

An official cause of death was not announced pending the medical examiner’s ­report.
