Yamaha Grizzly: four-wheeler (ATV), generations and what to check when buying used

Yamaha YFM Grizzly — a four-wheeler (ATV) produced since 1998, designed for work, hunting, and off-road driving. We look at the generations, engines, and what to check when buying used.

Grizzly in brief

The Grizzly is Yamaha's 'utility' class four-wheeler, designed for both farm and forest work and off-road driving. It features a robust construction, front and rear cargo areas, and a transmission with four-wheel drive.

The range includes several models with different engine sizes (from mid-range to 700 cm³), so you can choose according to your needs — from lighter work to heavier off-roading.

Generations — what's the difference

The first Grizzly 600 (from 1998) had a carburetted engine. Later Grizzly 660 (2002–2008) models were more refined, and from 2007, the Grizzly 700 with fuel injection appeared.

Since then, the range has expanded with models featuring smaller engines (350, 450, 550) and an electric power steering system (EPS). Newer models offer more comfort, improved suspension, and better handling.

Engine and transmission

The engine is a liquid-cooled, four-stroke, single-cylinder unit with a capacity depending on the model (e.g., around 595, 660, or 686 cm³). It delivers strong low-end torque, ideal for work and off-roading.

The transmission is an automatic with an Ultramatic belt, offering 2WD or 4WD modes, and some models feature a differential lock. Engine braking helps when descending hills.

What to check when buying a used Grizzly

Check the gearbox: movement should be smooth, without judders or vibration. Test 2WD, 4WD and differential lock modes, and check if the power steering (EPS) works, if fitted.

Inspect the chassis, suspension, wheel arches, driveshafts and protective rubber gaiters for cracks. Check the brakes and tyres for leaks and signs of water ingress, and the mileage (or engine hours) against the service book.
