    Effortless transmission

    Perfect for young or inexperienced riders, a fully automatic gearbox makes the YFM90R even easier to ride. This is especially useful over longer distances, when shifting can become tiring.

  • alt

    electric start

    Start-up is as effortless as handling and maintenance are. No need to worry about a kickstarter, simply press the electric start and the YFM90R springs into life. It's ideal for learner riders from 10 years old.

    Forward, Neutral and Reverse

    The YFM90R is equipped with an F/N/R gears lever, allowing for extra rider convenience.

    Long travel adjustable suspension

    Long-travel suspension helps keep the tyres in contact with the ground, even on undulating terrain. Independent front suspension means that the movement of one front wheel is not affected by that of the other. This improves handling by allowing the YFM90R to track across bumpy terrain more accurately and smoothly for increased comfort and control.

    Wide chassis & great ground clearance

    Compact engine designs and long travel suspension keep Yamaha ATVs riding high over rough ground. A wide chassis ensures great stability. Strong skid plates help to protect the ATV engine and chassis from damage if an obstacle is encountered.

    Ergonomic design

    Piloting an ATV brings an unusual combination of muscles into play. The YFM90R is designed to accommodate riders of varying sizes and weights from age 10 and upwards.

  • alt

    Low maintenance engine

    Kids want an ATV that's ready for them to use, whenever they feel like it. The YFM90R uses an 88cc single-cylinder, 4-stroke engine that's been specially designed to require minimal maintenance and provide maximum reliability. Power transmission is via a reliable chain drive system.

ATVs with engines up to 70cc are recommended for use only by riders 6 years and older and always with adult supervision. ATVs with engines of 70 to 90cc are recommended only for use by riders 10 years and older, and always under adult supervision. ATVs with engines of 90cc or greater are recommended for use only by riders 16 years and older. ATVs are built to operate within their design limits. Safe towable weights, together with maximum carrying capacity are identified in the owner's manual if applicable. For durability, reliability, but most important of all, operator safety, under no circumstances should the recommended capacities be exceeded. Yamaha recommends that all ATV riders take an approved training course. For safety and training information, see your dealer or call your Yamaha Distributor in your country. ATVs can be hazardous to operate.
