The Mongoose 90S is a slick youth-sized sport quad that comes with serious GNCC and ATV Motorcross racing credentials. Powered by an air-cooled and carbureted 89cc 4-stroke engine, and operated via an easy to use automatic CVT with F-N-R, the chain-drive Mongoose features a single A-arm front and swingarm rear suspension mated to preload adjustable shocks, 18x7-8 front/18x9-8 rear tires, and front drum and rear disc brakes with safety lock. Electric start makes it a cinch to fire up and an auto-stop safety lanyard keeps the fun in check. Additional parental controls include screw-type throttle limiter and CVT collar allows an adult to set speed and power limits to suit their child’s skill and experience. Available in Red or Blue.
