New 2016 WR450F

NEXT GENERATION ENDURO WITH YZ DNA

 *Price still to be confirmed*

Rightfully Wrong Last year Yamaha made clear its intention to move back to the top table of the enduro world with the launch of the eagerly-awaited WR250F. Featuring a completely new engine and chassis, the WR250F achieved an impressive streak of top 5 results – including multiple podium finishes in the 2015 Enduro World Championship – underlining its competitiveness at the very highest level. For the 2016 season Yamaha further reinforces its comprehensive off road line up with the arrival of the all-new WR450F, a sophisticated enduro racer that benefits from some of the most advanced engine and chassis technology to be seen in its category. Based on the 2015 MXGP World Championship winning YZ450F – and developed alongside the latest 2016 YZ450F production model – the all-new WR450F utilises Yamaha’s innovative reverse cylinder head and rearwards slanting cylinder. Having convincingly demonstrated its winning performance at the highest level, this industry-leading engine design gives the WR450F rider high levels of controllable and linear torque, while this design’s greater mass centralisation contributes towards the bike’s agile handling character.

2016 WR450F Model Overview * All-new enduro / rally model benefitting from the latest Yamaha technologies * Aggressive and modern YZ450F-inspired ‘Rightfully wrong’ design concept * Industry-leading ‘reverse’ engine layout * Compact, mass centralised design delivers light and agile handling feel * Linear torque for easy to control engine performance * Enduro suspension settings give stable and confident handling feeling * MXGP World Championship winning DNA *

NEW WR450F ENGINE Linear torque with deep reserves of power Like the YZ-F models and the recently launched WR250F, the completely new WR450F engine features a reverse cylinder head with a front facing air intake and rear-exiting exhaust. By increasing intake and exhaust efficiency, this innovative layout enhances the engine’s linear torque feeling, and delivers deep reserves of highly controllable and easy-to-use power. Dubbed the ‘Rightfully wrong’ concept by Yamaha, the WR450F’s reverse cylinder head and rearwards-slanting cylinder layout has already proved its competitiveness with the World Championship winning YZ450F motocrosser. As with the highly successful YZ-F ‘brothers’ and the WR250F enduro, the new WR450F’s compact engine layout – together with the under seat fuel tank and snaking exhaust pipe – contributes significantly towards mass centralisation.

Compact size with centralised mass the configuration of the new rearwards slanting engine has enabled Yamaha’s designers to construct a compact new chassis that capitalises on the handling performance gains offered by the engine’s more centralised mass.

Wide-ratio 5-speed transmission and light enduro clutch Equipped with a new wide ratio 5-speed transmission, the WR450F is ready to master any terrain – from slow speed woods riding through to aggressive special tests – as well as being able to achieve a good top speed on open enduro and rally terrain. Compared to the previous WR450F, the new model runs with higher 2nd, 3rd and 4th gears, while 1st and 5th remain the same. To complement its wide-ratio transmission this next generation enduro bike features an all-new enduro clutch that’s designed to handle the long and hard days experienced in a typical event. For a light feel together with good durability, the new clutch uses new materials for the friction plates and clutch disc, as well as a newly added push lever.

 

KYB® Air-Oil-Separate (AOS) front forks with dedicated enduro settings In the motocross world, the Yamaha YZ450F’s Air-Oil-Separate (AOS) front forks are widely regarded as being amongst the very best designs available today. By keeping the air and oil in separate chambers, these high-tech forks help to prevent cavitation for more stable damping performance and predictable handling characteristics.

Lighting and instruments The WR450F is equipped with a full lighting kit, and to handle the extra demand on the electrical system, a high output ACM is fitted. The lightweight digital instruments include a multi-function display with an enduro computer that keeps the rider informed about their progress and distance covered – while a fuel level warning lets the rider know when it’s time to refuel. There’s also a main switchfree starting system for speed and convenience.

 

18-inch rear wheel and enduro tyres Featuring black rims, the WR450F’s 18-inch rear wheel and 21-inch front wheel are equipped with Metzeler 6 Days Extreme tyres, and the enduro equipment also includes a lightweight engine guard, frame-mounted sidestand, sealed chain and 22mm rear axle. Slim bodywork and durable in-mould graphics The WR450F’s body features a long, flat seat and a slim front section for easy body weight shifting, enabling the rider to maintain high levels of control when braking, accelerating and cornering. The 4-position adjustable handlebars enable the rider to select the right set up to suit their style and physical size, and the recessed fuel cap allows the seat to be extended further forwards, allowing even greater freedom of movement.

Large diameter 270mm front disc brake Like the latest 2016 YZ-F models, the all-new WR450F is equipped with a 270mm diameter front disc brake that offers excellent stopping performance together with accurate feel.
