Yamaha WR450FSP for Sale at Bike and Power Yamaha in Dural, NSW | Specifications and Review Information
In recognition of the WR450F's importance to the Australian market, Yamaha has created a special limited edition version for 2021. The unique Aussie Edition comes with striking blue graphics featuring a kangaroo motif and a range of Australian sourced accessories.
The Aussie Edition model is based on the recently announced all new 2021 WR450F and will be strictly limited to 400 units. Each model is stamped with its own unique collector's number. The look is pure antipodes with a kangaroo motif featuring in the embedded graphics as well as the custom anodised aluminium radiator guards and bashplate - developed locally by Force Accessories. Fellow Aussie firm Barkbusters supplies the handguards and an Akrapovic muffler is specified for this very special model.
MORE POWERFUL AND COMPACT NEW 450CC ENGINE
Already renowned for its enormous power output, the WR450F engine has been thoroughly redesigned for 2021 to deliver stronger and more controllable performance. The new engine is essentially the new generation YZ450F tuned with enduro settings - which means its significantly more compact and lighter than the 2020 engine. The revised configuration enhances the bike's mass centralised design to make it one of the easiest-handling large capacity enduro machines. Featuring increased compression ratio - up from 12.8:1 to 13:1 -the reverse cylinder head also runs a durable forged piston and aggressive cam profiles. New intake/exhaust systems and ECU run WRF specific settings to deliver the best balance of race-winning performance together with ultimate controllability for tight trails.
NEW LIGHTER CYLINDER HEAD
The new cylinder head weighs 310g less than before and is significantly more compact. Because this innovative design is positioned close to the bike's mid-section it helps to achieve an idealised mass centralisation, and this contributes enormously towards the WR450F's dynamic handling characteristics. The intake/exhaust valve angles and intake port design are changed and a new piston with a small recess is specified to create a more concave combustion chamber for increased power. This new high-efficiency head with its long and straight inlet, produces a fine balance of power with exceptional controllability.
HANDLEBAR-MOUNTED MAP SWITCH
The 2021 WR450F features a handlebar-mounted mapping switch (blue button) that enables the rider to select one of two power maps on the fly. This simple adjustment allows instant engine delivery changes to suit variable terrain or weather conditions. For example, from an aggressive map for fast dry conditions to a high traction map for slippery hillclimbs.
COMPACT ELECTRIC STARTER
The new 450 engine is equipped with a compact and lightweight electric starter that gives push-button convenience for hassle-free starts - especially useful on the side of a hill.
In 2019 the WR450F became the first enduro bike with inbuilt connectivity featuring remote wireless tuning using a smartphone. Now the 2021 model continues to lead the field in digital technology. By downloading the free Power Tuner app for IOS or Android devices, WR450F riders can easily adjust the fuel/air mix and ignition timing to set the bike up for different riding conditions. This feature makes the 2021 WR450F the most adaptable enduro machine – and one that can be tuned instantly on the trail, allowing riders to make the most of a wide range of surfaces and weather conditions. In addition to its engine re-mapping function, the Power Tuner app can also record information and monitor a range of data, including system diagnosis, engine run time and more, making it an indispensable part of every rider's toolkit.
