Powerful engine

Big power lies at the heart of the Grizzly 450 IRS. The liquid-cooled 421cc engine offers the kind of low-rpm torque needed to get the heaviest loads moving. In addition, Ultramatic® transmission supplies engine braking to your ATV’s driven wheels especially on steep, downhill working areas.

Lightweight frame

A one-piece frame reduces weight as well as being strong and rigid construction. It incorporates an extra-durable rear gear assembly, connected at three (rather than the normal two) separate points for best-ever protection against the strains of regular, heavy-duty use. A short, springy stabilizer bar offers increased support.

Multi-disc wet braking

Yamaha’s sealed oil-bathed multi-disc brake setup is ultra-durable, and protects the system from becoming clogged with the mud or stones that are thrown up during use. It also provides stronger, more consistent stopping power and is easier to adjust.

On-Command® drive system

Yamaha’s push-button On-Command 2WD/4WD system (with locked-differential 4WD) lets you switch between drive modes, giving near-instantaneous transition from cruising to climbing.

Independent Rear Suspension (IRS)

Independently linking each individual rear wheel to the chassis means that the movement of one wheel is not affected by the movement of the other. This helps the ATV to soak up uneven terrain. It’s a major contributor to rider comfort and peace of mind.

Digital LCD multifunction display
