YFM90R ATV 2018

The kids' ATV that adults love too.

The YFM90R may be small in size, but it's equipped with several features found on larger Yamaha models - including double A-arm independent front suspension, CVT transmission and electric start.

The YFM90R balances power with a range of features to give you total peace of mind. A simple CDI plug-in adjusts engine power output to suit different riding abilities while a parking brake on the handlebar ensures that the YFM90R stays exactly where you last left it.

The fully automated gearbox makes it even easier to ride and it's thinking like this that makes YFM90R the kids' ATV that adults love too.

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.
