Grizzly 450 EPS

Key Features

Features Gallery
  • alt

    Lightweight frame

    The one-piece frame reduces weight as well as being a stronger and more 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, spring stabilizer bar offers increased support.

    Electronic Power Steering (EPS)

    On long days or in difficult terrain, EPS helps every rider of any body size. The system uses rider and wheel input to assist steering, provides feedback, prevents handlebar slaps and the high-output AC generator guarantees power supply in all conditions. The EPS is the same version as the Grizzly 700's but with a revised ECU mapping.

  • alt

    On-Command® drive system

    Yamaha's push-button On-Command® 2WD/4WD system (with locked-differential 4WD) lets you easily switch between drive modes, giving near-instantaneous transition to adapt to changing riding and surface conditions.

  • alt

    Independent long-travel adjustable suspension

    Long-travel suspension ensures tyres are in consistent contact with the ground even on tricky terrain. The Grizzly 450 EPS' double A-Arm front suspension and Independent Rear Suspension adapt to all surfaces and offer massive ground clearance. Pre-load adjustability optimizes handling for all riders and loads.

  • alt

    Multi-disc wet braking

    The durable sealed oil-bathed multi-disc brake setup protects the system from clogging by mud or stones thrown up during use. It provides strong and consistent stopping power and is easy to adjust.

  • alt

    Powerful engine

    Substantial power lies at the heart of the Grizzly 450 EPS. The liquid-cooled 421cc engine offers the kind of low-rpm torque whenever you need and wherever you need it. In addition, Ultramatic® transmission provides outstanding engine braking on even the steepest working areas.

  • alt

    Comfort and practicality

    The lightweight seat designed for cold-weather riding comfort, plus a range of durable, practical accessories - such as winches, plough, lighting kits and battery chargers - help take the strain out of your busy working day.

  • alt

    Excellent cargo capacity

    Offering generous storage capacity, the Grizzly 450 EPS can carry a maximum payload of 120 kg - 40 kg at the front, and 80 kg at the rear. A lightweight hitch mount is capable of towing heavy loads up to 600kg

ATVs with engines up to 70cc are recommended for use only by riders 6 years and older and always with adult supervision. ATVs with engines of 70 to 90cc are recommended only for use by riders 12 years and older, and always under adult supervision. ATVs with engines of 90cc or greater are recommended for use only by riders 16 years and older. ATVs are built to operate within their design limits. Safe towable weights, together with maximum carrying capacity are identified in the owner's manual if applicable. For durability, reliability, but most important of all, operator safety, under no circumstances should the recommended capacities be exceeded. Yamaha recommends that all ATV riders take an approved training course. For safety and training information, see your dealer or call your Yamaha Distributor in your country. ATVs can be hazardous to operate. For your safety: always avoid paved surfaces. ATVs are designed for unpaved surfaces only. Riding on paved surfaces may seriously affect handling and control and can cause loss of control. Always wear a helmet, eye protection and protective clothing. Never carry any passengers. Never engage in stunt riding. Riding and alcohol/drugs don't mix. Avoid excessive speed and be particularly careful on difficult terrain. Please 'tread lightly': always ride in a responsible manner, respecting the environment as well as country and local laws. The riders in this brochure are professionals: don't attempt to emulate them. The specification and appearance of Yamaha products will be varied from time to time without notice, and as shown here are illustrative only and are not a contractual description of products. Some models are shown with optional accessories. All ATVs come with a 12-month Limited Factory Warranty, except for Banshee, which carries a 90-day Limited Factory Warranty.
