Market Background and Product summaries

With their characteristic low-pressure balloon tires, ATVs have the performance capability to tackle all kinds of off-road terrain, whether its unpaved or hilly ground, rock beds, sand, grass lands or frozen roads. That is why they are used for a wide range of uses from outdoor leisure and sport riding to transportation, hauling loads and patrol duties. In recent years the domestic demand for these vehicles in Japan is about 500 units annually (Yamaha survey).

Presently, Yamaha offers a lineup of eight ATV models ranging in engine displacement from 50cc to 700cc in the two basic categories of utility models designed for a variety of jobs and sports models designed for leisure sport riding.

The "GRIZZLY 700FI" now being released on the Japanese market was previously released in 2006 on the European and North American markets to high acclaim as the flagship utility model of the Yamaha ATV lineup.

It mounts a 700cc liquid-cooled SOHC, 4-valve single-cylinder engine with F.I. (fuel injection) on a newly designed frame and adopts the E.P.S. (electric power steering) system, along with other features inherited from the existing GRIZZLY 660 like the Yamaha-exclusive drive mode switching system and a fully automatic transmission. The result is a model that provides not only outstanding off-road running performance but also new levels of enjoyment, smoothness and comfort in use.

Main Features of the GRIZZLY 700FI

SOHC single-cylinder engine with F.I. (fuel injection)
The 700cc SOHC 4-valve, single-cylinder engine is equipped with F.I. (fuel injection) that enables stable fuel supply at all times and a single-axis balancer. This power unit delivers gutsy torque from the low-speed range and plenty of usable power on up, while also providing reduced vibration and quieter performance.

Yamaha exclusive drive and transmission systems
This model's "On-command" system allows the rider to switch between the three drive modes of 4-wheel drive, 2-wheel drive and differential lock with a simple switch action. The "Ultra-matic" V-belt automatic transmission is another exclusive Yamaha system that provides stable engine-brake performance even on downhills.

E.P.S. for improved drivability and comfort

This model adopts the E.P.S. (electric power steering) system to provide smooth steering under all kinds of riding conditions. This ensures a ride with even more pleasing drivability.

Chassis designed for optimum weight distribution and reduced weight
A newly designed high-tensile steel frame and positioning the fuel tank below the seat have made it possible to optimize weight distribution while also achieving the lowest level of body weight in class. All of this contributes to outstanding handling characteristics.

New suspension design for outstanding off-road performance
The 4-wheel separate double wishbone suspensions with a newly designed rounded type A arm achieves a minimum ground clearance of 275 mm and wheel travel of 180mm for the front wheel and 230mm in the rear that contribute to excellent off-road running performance.
