A middleweight utility ATV with heavyweight ability – that’s the Grizzly 550.
The bear incorporates most of the advanced riding technology features of Yamaha’s biggest and most powerful ATV, the Grizzly 700, but is powered by a compact 558cc four-stroke single engine.
This advanced powerplant is built to deliver an ideal combination of low running costs and high-traction torque through the rev range to help the new Grizzly 550 appeal to a wide cross-section of ATV users.
The four-valve engine features a new crankshaft that’s been reprofiled for even smoother running, a new cylinder head with a long-reach spark plug for easy starting, and EFI fuel injection for better emissions and lower fuel consumption.
Yamaha’s three-position push-button On Command drive system offers a choice of 2WD, 4WD, or 4WD with differential lock to keep Grizzly 550 going across the most difficult terrain. And fully automatic Ultramatic™ transmission makes forward motivation both simple and controllable.
Industry leading all-round double-wishbone independent suspension help all wheels stick to the deck to increase traction when the going gets tough, while all wheel disc brakes feature with shaft drive for ultimate user friendliness.
Yamaha’s variable-resistance Electronic Power Steering (EPS) takes the stress out of everyday tasks, no matter how much work a user packs into a Grizzly 550 day. And that’s a lot, thanks to the 20-litre underseat fuel tank and even better ergonomics including a redesigned seat, throttle control and transmission shift lever, plus new arm guards front and rear to optimise durability. A tough digital instrumentation pod provides a full rundown of speed, engine hours, fuel and transmission status, and a double trip meter.
Cargo racks front and rear join a big range of optional accessories including bulldozer blades, power winches, skid plates and brush guards to build on Grizzly 550’s already impressive functionality.
A dead ringer for its legendary big brother the Grizzly 700, just about the only thing that isn’t full-sized on the Grizzly 550 is the price.
- The 500-600cc class has a new leader, with a fully featured package based on its best-selling bigger brother, the Grizzly 700 FI, with a new 558cc powerplant and offering plenty of grunt.
