HIGHLIGHTS

CAPABILITY The Ultramatic® transmission is specifically tuned to provide lowered cruising rpm for smooth, quiet operation, and features a gated shifter with park, dual-range (Hi/Lo) drive and reverse gear. Even the position of the gated shifter was carefully considered, being moved forward to provide a roomier rider area.

COMFORT The Kodiak 450 offers a riding position with the same roomy feel as the larger Kodiak 700. With tall handlebars, a seat that is long and plush for improved rider comfort, and large textured floorboards, every aspect of the Kodiak 450 was designed to bring class-leading levels of refinement to the middleweight 4x4 ATV segment.

CONFIDENCE Yamaha ATVs feature marine-grade waterproof connectors for maximum weather-proofing, increased durability and improved serviceability.

CONFIDENCE The Kodiak 450 transmission uses its own cooling intake to maintain proper temperatures, an oversized belt to handle the torque of the large motor and Yamaha’s unique sprag clutch to maintain constant belt tension. The end result is a drivetrain built for years of trouble-free service that leaves the competition in the dust, and is backed by the industry's only 10-Year V-Belt Limited Warranty.

FEATURES_&_BENEFITS

ENGINE 421 cc, liquid-cooled, SOHC, 2-valve, fuel injected, single Proven design with an excellent reliability record Engine uses regular unleaded fuel Rubber engine mounts reduce vibration & noise for excellent rider comfort Electric starting Includes auto decompression system for fast, easy starts SOHC, 2-valve cylinder head design Simple 2- valve design (1-intake & 1-exhaust) 40 mm intake & 34 mm exhaust valves Rocker arm valve actuation... simple, proven design that is easy to adjust Aluminum cylinder body with cast iron liner Cylinder can be over bored in the event of an issue (2 sizes of overbore available) Short skirt forged aluminum piston Lightweight design means faster throttle response & less mechanical vibration Gear driven engine balancer shaft Reduces engine vibration for improved rider comfort 34 mm Mikuni throttle body fuel injection system with TPS & ISC TPS (Throttle Position Sensor) is used to more precisely calculate the fuel injection quantity for optimum power, excellent throttle response & reduced fuel consumption ISC (Idle Speed Control) helps ensure a steady idle even during warm up Other fuel injection benefits include; choke-free starting, excellent fuel economy & reduced emissions Throttle limiter Easy to adjust, screw-type throttle limiter Throttle limiter reduces acceleration & top speed if desired High mounted, high capacity air box with washable foam air filter No tools required to access air filter Washable foam filter can be re-used reducing tune-up costs High mounted design helps prevent water ingestion Air box features a "no tools required" drain Yamaha's industry leading Ultramatic® CVT (fully automatic) dual range transmission with reverse & downhill engine braking Dual range, high - low transmission with reverse. Low range offers more "grunt" for towing or hauling heavy loads or when tackling technical terrain CVT automatically selects the optimum transmission ratio, meaning you are always in the right "gear" Ultramatic® design offers controllable, confidence inspiring downhill engine braking Downhill engine braking also reduces brake wear & related servicing Ultramatic® design utilizes a special centrifugal clutch which keeps constant tension on the V-belt, reducing belt wear since the belt does not slip as the clutches engage High mounted belt cooling ducts help prevent water ingestion V-belt housing has an easy access "no tools required" drain plug Automotive style, gated, 5-postion shifter (high, low, neutral, reverse & park) Straight design front & rear drive shafts Straight driveshaft layout eliminates U-joints, reducing friction, noise & vibration Front & rear CV drive shafts feature heavy duty plastic boots to protect the CV joints from mud & water penetration for extended service life High capacity cooling system with electric cooling fan 53% more cooling capacity than the last generation Kodiak 450 Maintains consistent engine temperatures for optimum performance Radiator is positioned high in the frame for protection Design reduces heat reaching the rider Wet sump lubrication system Spin on type oil filter for fast, easy oil changes Oil drain plug access hole in skid plate Maintenance-free transistor controlled TCI ignition Produces a strong spark for fast starts Provides precise ignition timing / mapping for optimum engine performance at all rpms Marine style, waterproof connectors on key electrical components. Stainless steel exhaust system with catalyzer & cleanable spark arrestor Spark arrestor prevents stray sparks from exiting the exhaust Catalyzer reduces exhaust emissions Stainless steel design helps prevent rusting Air Injection System (AIS) injects fresh air into exhaust port to fully burn any unburnt fuel, reducing exhaust emissions
