An extreme edition for extreme adventures, complete with factory-installed WARN® winch, Special Edition paint, color-matched wheels and aggressive tread pattern GBC® Dirt Commander® tires.

  • Compact, 847cc, liquid-cooled, DOHC, 8-valve, inline twin cylinder engine provides lots of torque across the rev range with linear throttle response.
    • Features Yamaha’s Chip Controlled Throttle (YCC-T)
    • compact engine design allows it to be placed in the centre of the chassis allowing a shorter wheelbase for excellent off road capabilities
    • engine is designed to provide smooth, quiet operation for maximum enjoyment
    • 4-point rubber engine mounts reduce vibration
  • 4-valve design maximizes flow into & out of combustion chamber
    • 31.5 mm intake & 26.5 mm exhaust valves
    • stainless steel valves feature an Isonite surface treatment & carburized tips for excellent durability & wear resistance
  • Lightweight hollow camshafts.
    • cam profiles are designed to accentuate torque & power throughout the rev range
    • automatic cam chain tensioner reduces both mechanical engine noise & maintenance
  • “Cross Plane Concept” 270 degree crankshaft.
    • design reduces inertia torque while emphasizing linear torque
    • design has been optimized to achieve strong torque over a broad rpm range
    • CP Concept offers excellent “drive-ability” and linear throttle response
  • Lightweight gear driven balancer shaft.
    • reduces engine vibration for excellent rider / passenger comfort
    • reduced vibration also improves engine durability
  • Forged connecting rods feature a “nut less” design.
    • rods are heat treated for excellent durability
  • Lightweight, concaved forged aluminum short skirt pistons.
    • design aids in fast engine response & reduced mechanical vibration
    • excellent durability
  • “Liner less” bores with direct nickel ceramic plating sprayed directly on the aluminum block.
    • design eliminates the need for liners / sleeves & reduces weight
    • excellent heat dissipation & durability for consistent power delivery
    • cylinder block is incorporated into the upper engine case to reduce weight
  • Offset cylinder design.
    • cylinder is “offset” relative to the crank (toward exhaust side)
    • offset design reduces the side load (friction) on the pistons during the power stroke for improved power output & excellent fuel economy
  • Dry sump lubrication system with heat exchanger type oil cooler.
    • oil tank baffling system prevents oil starvation in rugged /difficult off road environments
    • dry sump oil system reduces engine height for a lower centre of gravity (no deep design oil pan)
    • heat exchanger type oil cooler maintains consistent oil temperatures for improved durability
    • spin-on type oil filter for fast oil changes
  • Yamaha Chip Control Throttle (YCC-T) system (a.k.a. “fly by wire throttle”).
    • YCC-T electronically controls the throttle valves for outstanding throttle response
    • YCC-T provides precise control of intake air volume for a smoother torque curve
  • “Closed loop” dual 36 mm Mikuni throttle body fuel injection.
    • system uses a throttle position sensor (TPS) for optimum performance (TPS is linked to the ECU & ignition mapping)
    • 12 hole injectors for optimum fuel atomization
    • system is “tuned” to provide excellent “drive-ability” & “linear” throttle control
    • fuel injection benefits include choke-free starting, steady idling during warm up, excellent fuel economy & reduced emissions
  • Easy access, high mounted, high flow 11.5 litre air box features primary & secondary air filters.
    • primary filter is a washable foam design, secondary filter is a wet viscous paper filter
    • no tools, clip-style air box lid for easy access
    • air box & ducting are designed to reduce intake noise
    • no tools required air box & duct work drains
  • Yamaha’s industry leading “Ultramatic” CVT (fully automatic) 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
    • engine braking also reduces brake wear & servicing
    • Ultramatic design features a special centrifugal clutch which keeps constant tension on the V-belt to reduce 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 a “no tools required” drain plug
    • automotive style, gated, 5-postion shifter (high, low, neutral, reverse & park)
  • Super convenient, servo motor controlled, push button On Command 4WD drive system.
    • On Command drive system features 3 modes: 2wd, 4wd limited slip & 4wd differential lock
    • On Command drive system lets you select the best mode for the conditions… not the machine
    • 4wd differential lock provides power to all 4 wheels for maximum traction and “bite”
  • Hi-low- reverse transmission features helical cut gears.
    • helical cut gears reduce mechanical noise & provide smooth, easy shifting
    • transfer case style transmission (separate transfer case bolts to engine)
    • console mounted, automotive style gated shifter (H-L-N-R)
  • Heavy duty front & rear drive shafts & new design front & rear gear cases.
    • single piece front & rear drive shafts
    • ring & pinion gears use a spiral design to reduce noise
    • front & rear CV drive shafts feature heavy duty “Peest” rubber boots to protect the CV joints for extended service life & durability
  • High flow, high efficiency cooling system with recovery tank.
    • high mounted rad & special rad side covers offer maximum rad protection
    • 7 – blade ring type cooling fan for maximum airflow through the rad
    • under hood access panel & drain cut-out built into the rad shroud for easy rad cleaning
    • over heat warning buzzer
  • Quiet, full stainless steel 2 into 1 exhaust system.
    • system features a cleanable spark arrestor to prevent stray sparks from exiting the exhaust
    • 3-way catalyzer & oxygen sensor (closed loop fuel injection) help reduce exhaust emissions
    • stainless steel design helps prevent rusting
  • Maintenance-free transistor controlled ignition (TCI).
    • produces a strong spark for fast starts
    • provides precise ignition timing / mapping for optimum engine performance at all rpms
  • High performance direct ignition coils (ignition coil is built into the spark plug caps).
    • reduces weight & complexity
  • Speed Key (a.k.a.) Valet Key.
    • limits vehicle top speed to 40 km/hr (25 mph) when Speed Key is on
    • under hood key operated system (key is removable to prevent tampering)
  • High output AC magneto.
    • AC magneto produces 600 watts of power for the vehicle & related optional factory accessories
