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.

Effortless transmission

Features 1

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.

Electric start

Features 2

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

Features 3

The YFM90R is equipped with F/N/R gear levels, allowing for extra rider convenience.

Long travel adjustable suspension

Features 4

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

Features 5

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

Features 6

Piloting and ATV brings an unsual combination muscles into play. The YFM90R is designed to accomodate riders of various sizes and weights from age 10 and upwards.
