2018 Yamaha YFZ50


With electric start, automatic transmission and parental controls, the YFZ50 offers the ultimate sport ATV experience to riders 6-years old and up.

Additional Features

  • MODERN, RELIABLE ELECTRONICS: The CDI system means reliable ignition performance, with a strong, efficient spark, and a sealed, maintenance-free battery gives worry-free service.
  • YAMAHA SPORT ATV DNA: The YFZ50 offers the same sporty looks as the rest of the YFZ family, for exciting sport ATV style.

Chassis and Suspension

  • SPORTY CHASSIS: Single I-arm front suspension is tuned for light, easy steering and comfortable ride quality. The rear swingarm also features a compact single shock rear suspension for good control and comfort. And the entire package includes awesome YFZ-derived sport ATV styling.
  • COMFORTABLE ACCOMMODATIONS: The YFZ50 is designed to be comfortable and accessible for new ATV riders. With its roomy ergonomics, plush seat and wide floorboards, riders 6 and up won’t outgrow the machine before they’re ready for more displacement when they’re older.
  • OPTIMIZED TIRES: Duro® low-profile tires, AT16 x 6.5-7 front and AT16 x 7-7 rear, give YFZ50 aggressive looks and sporty handling.
  • SECURE STOPPING POWER: For reliable stopping power, three sealed drum brakes bring the YFZ50 to a secure stop. There’s a handlebar-mounted parking brake, too.


  • ENGINE LIMITER AND TETHER SWITCH: To help young beginners grow into accomplished ATV riders, the YFZ50 includes a two-stage rpm limiter as well as a throttle limiter to restrict the engine’s performance and adapt to the rider’s advancing skill levels. A tethered switch allows parents to closely monitor new riders and cut power to the engine if necessary as new riders learn the basics of ATV control.
  • ROBUST 49CC ENGINE: The 49cc four-stroke SOHC engine is tuned to develop excellent low- to-mid-range performance, just where it’s needed. The motor is air-cooled for simplicity, performance and long engine life and it uses ultra- reliable wet-sump lubrication.
  • ELECTRIC STARTER: Push-button electric starting comes standard, powered by a reliable sealed battery, and a kick starter is provided for additional peace of mind.
  • AUTOMATIC TRANSMISSION: Fully automatic, continuously variable transmission (CVT) means no shifting. Handy for all riders, it’s a feature new riders will particularly appreciate.
  • SPORTY DRIVETRAIN: Engine power is transferred to the rear wheels via a robust O-ring chain drive, running along a swingarm that’s set at an optimized angle for rear shock performance.
  • LOW MAINTENANCE DESIGN: Servicing is easy, thanks to features like the tool-less quick-access air filter element. The exhaust includes a standard spark arrestor as well.

Top Features

  • BEGINNER-FRIENDLY FOUR-STROKE PERFORMANCE: The YFZ50™ is engineered as the ideal starting point for aspiring ATV riders aged 6 and up, with a low-maintenance 49cc engine tuned to develop responsive, controllable performance. A combination of engine limiters and a power cut-off tether switch make it easy to allow young riders to adapt to the ATV as their skills grow.
  • REDUCED MAINTENANCE DESIGN: Servicing is simple, too, thanks to features like the tool-less quick-access air filter element.
  • SCALED DOWN, NOT SCALED BACK: Single I-arm front suspension is tuned for light, easy steering and comfortable ride quality. The rear swingarm also features a compact single shock for good control and comfort. It also boasts convenient features like a fully automatic CVT transmission and electric start with a back-up kickstart.
  • COMFORTABLE CHASSIS: A robust steel frame design incorporates a large 1.5 gallon fuel tank, plush seat and roomy integrated floorboards. Yamaha Sport ATV DN
