The Grizzly 700 EPS is a true All Terrain Vehicle. With a dry weight of 272kg, this rugged and reliable machine allows the driver to take control in a wide range of situations. With its lively and more powerful engine, and a redesigned suspension set up and lighter steering, this truly versatile ATV delivers greater comfort and reduced fatigue when working, and gives more enjoyment and confidence on the harshest terrain.
The Grizzly 700 EPS rugged steel frame is now equipped with additional gussets which increase overall chassis rigidity to adapt to the wider wheel track. Among the benefits of the new suspension package and the wider wheel track are higher levels of stability and increased riding comfort, making the new Grizzly 700 EPS a better performer in leisure and commercial situations.
Yamaha's engineers have also focused on making the Grizzly 700 EPS cleaner, leaner and meaner, and the 686cc single-cylinder liquid-cooled SOHC engine has undergone a wide range of technical modifications in almost every key area. Torque and horsepower output are both increased due to a number of changes to the engine design. An all-new camshaft features completely revised valve timing with reduced overlap, and a new single-port head is used. The redesigned cylinder head features a pent roof combustion chamber, and together with a new lighter forged piston these changes give an increased compression ratio, up from 9.2 to 10.0:1.
Raptor-based four-valve combustion chamber design produces a potent combination of low-rev torque, right-now throttle response and high horsepower.
Compact engine design features a 35-degree cylinder angle for ground clearance and lower seat height for quick steering and manoeuvrability.
Electronic fuel injection provides a perfect fuel/air mixture to provide easy cold starts and flawless fuel delivery in virtually any condition between sea level and 15,000 feet.
New cylinder head/piston/camshaft configuration allows the engine to achieve strict EPA emissions standards. Also playing a crucial role making this 686cc engine cleaner is the honeycomb catalyser, as well as the Air Induction (AI) system which introduces fresh air into the exhaust port to ignite any unburned hydrocarbons.
The new installed ECU features redesigned fuel injection and ignition mapping, as well as new software for the new AI system, and a port and connector for the new Yamaha Diagnostic Tool.
One of the most significant chassis changes is the use of a new lightweight suspension design that features 30mm longer upper and lower front and rear A-arms.
The front and rear wheels have an involute design, they feature newly-designed inward-rolled edges which are protected by the tyres. The advantage of this design is that it helps to prevent the build-up of dirt and other material on the wheel rim which can happen with outside rolled rim edges.
