Yamaha Grizzlys could not be easier to ride as they feature a fully automatic CVT type drive (Constantly Variable Transmission) which uses a low maintenance belt to transfer the power from the engine to the gearbox. The rider simply selects forward or reverse (just like on an automatic car)and then uses the thumb throttle to control the speed. Once on the move the Ultramatic system does all the work providing the optimal power required without the need for changing gear. It even incorporates a clever device which automatically engages to provide reliable all-wheel downhill engine braking power.
Easy to reach – gear selection
All Grizzly models have a conveniently located hand gear change lever so the rider can select Forward, Neutral or Reverse gear before setting off. On the Grizzly 350 4WD, 450, 550 and 700 models there is also a choice of High or Low (Dual Range) forward gears to tackle the toughest terrain or for use when towing big loads. In addition the 450, 550 and 700 models feature a Park position on the gear selection gate, rather than a Parking Brake on the handlebar lever, as fitted to the smaller models with cable operated rear brakes.
IRS – Independent Rear Suspension
On smaller models the rear wheels share a common axle but for the 450, 550 and 700 models where they are likely to encounter more extreme terrain, the IRS rear suspension system allows each wheel to move independently. This means one wheel is not affected by the movement of the other and each wheel can track the surface soaking up holes or bumps for better traction and a much softer and more comfortable ride.
You will find several different types of rear brakes on Yamaha ATV models. The larger 550 and 700 models employ double rear discs for the maximum possible stopping power as they are the largest machines with the greatest towing and carrying capacity.
The 450 Grizzly models utilise a single, sealed multi-disc rear brake (pictured) which works in the same way as a clutch with the friction plates running in an oil bath. The brake is incorporated into the rear gearbox, controlling both rear wheels via the drive shafts. Grizzly rear brakes all have dual controls with the rider being able to operate the rear brake with the left handlebar lever or via the footbrake pedal located in the right hand footwell. Additionally cable rear brakes are fitted with a Parking Brake lever on the handlebar.
At Yamaha we know that you are going to need a safe place to put your valuables – like keys or mobile phone. So you will find a variety of different storage solutions on each model including watertight lockers and underseat compartments.
Carrying and Towing
Grizzly racks vary in size but the biggest racks can carry loads up to 85kg. Finished in a durable black coating the designs incorporate small vertical stops so that loads don’t slide around. All models above 350cc come with a mounting point where a tow ball can be fitted. Towing capacities vary by model up to 600kg.
