2019 KODIAK 450

Power

• 421 cc, fuel-injected, single-cylinder engine was created to provide a balance of responsive power and all-day comfort.
• Backed by proven Yamaha reliability, the Kodiak 450 was built for the working or recreational rider.

Design

• Chassis styling fits a roomy riding position.
• A low centre of gravity and a light steering effort into one complete compact package.

TERRAINABILITY

• The Kodiak 450 features Yamaha’s On-Command® 4WD system.
• The driver-controlled system eliminates hesitation or slipping when engaged.

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)
• Convenient, handlebar mounted push button On Command 2wd – 4wd drive selector.
  • drive system features 2 modes: 2wd & 4wd limited slip
  • On Command system lets you select the best mode for the conditions… not the machine
• 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.
