The YFM90 (Yamaha Raptor 90) may be small in size, but it’s equipped with several features found on larger Yamaha models – including double A-arm independent front suspension, a rear disc brake, CVT transmission and electric start.

The YFM90 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 YFM90 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 YFM90 the kids’ ATV that adults love too.

Effortless transmission

Perfect for young or inexperienced riders, a fully automatic gearbox makes the YFM90 even easier to ride. This is especially useful over longer distances, when shifting can become tiring.

Electric start

Start-up is as effortless as handling and maintenance are. No need to worry about a heavy kickstarter, simply press the electric start and the YFM90 springs into life. It’s ideal for learner riders as from 12 years old.

F/N/R gears

The YFM90 is equipped with a F/N/R gears lever, allowing for extra rider convenience.

Long travel adjustable suspension

Long-travel suspension lets tyres maintain longer, more consistent ground contact, even on uneven 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 ATV to track bumpy terrain more accurately and remain in a level, controlled posture.

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 YFM90 is designed to accommodate a range of body shapes and types from age 12 and upwards.

Low maintenance engine

Kids want an ATV that’s ready for them to use, whenever they feel like it. The YFM90 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 12 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.
