Kai Spencer, a schoolboy from Manchester born on August 19, 2010, is very sporty and enjoys football, mountain biking, cars, engines, dirt bikes, and adrenaline sports. He rode his first jet ski at the age of 7. Racing with the number 14, chosen because he turns 14 this year, Kai began his racing career in 2024 and competes in the Vintage X2 class. His favorite race story involves his step-dad, Sam Merrell, breaking his back while racing and humorously asking for flapjacks as the first thing. For the 2024 season, he will be riding a 1995 Kawasaki X2 built by Fat Boy Jet Ski Shop, with sponsorship from Fat Boy Jet Ski Shop, KMC Animal Services, and CR Concrete.
