For 2020 the all-new YZ450F comes with less weight, more power, and sharper handling, making it the most competitive 450cc model that Yamaha has ever produced.
In order to create a motocross bike that can race and win at every level against the toughest opposition, Yamaha’s engineers have analysed every single component and made a wide range of major and minor improvements wherever possible.
As a result of this intensive part-by-part analysis the entire motorcycle has been subject to an extensive redesign, and the team of engineers has succeeded in achieving significant weight savings together with power gains and enhanced handling performance for the 2020 YZ450F.
More powerful and compact new 450cc engine
Already renowned for its enormous power output, the YZ450F engine has been thoroughly redesigned for 2020 to deliver stronger and more controllable performance. The new engine is significantly more compact and lighter, and the revised configuration enhances the bike’s mass centralized design to make it one of the easiest-handling open class motocross machines.
Featuring a high compression reverse cylinder head as well as a durable forged piston and aggressive cam profiles, the compact new 450cc engine is designed to deliver the best balance of race-winning performance together with ultimate controllability.
All-new rearward-slanted cylinder
One of the key engine improvements for 2020 is the new rearward-slanted cylinder that is both lighter and more compact. Because this innovative design is positioned closer to the bike’s mid-section it helps to achieve an idealized mass centralization, and this contributes enormously towards the YZ450F’s dynamic handling characteristics. The new rearward-slanting cylinder is equipped with a high compression bridge-box design piston, and together with the high-efficiency reverse cylinder head with its long and straight inlet, this industry-leading design produces a fine balance of 450-class power combined with exceptional controllability.
YZ250F: Tune, Race, Win
Following its complete redesign for 2019, the YZ250F is proving to be one of the most competitive 250cc 4-strokes, with Dylan Ferrandis winning the AMA Supercross West Championship. In the 2019 MX2 World Championship Yamaha YZ250F riders Jago Geerts and Ben Watson are amongst the main contenders, and at local and national level the YZ250F continues to impress.
Sporting an electric start, and a 250cc, liquid-cooled, four-stroke engine housed in an aluminum bilateral beam frame, as well as being suspended by industry leading KYB spring type forks and KYB rear shock, the 2020 YZ250F provides the ultimate balance of race-winning performance, rideability and comfort. It also continues to feature Yamaha’s advanced racing technology including dual-mode switchable engine mapping and wireless connectivity for the Yamaha Power Tuner App.
Other models in the 2020 Off Road range
Yamaha’s 2020 range is designed to give everybody the chance to enjoy the thrill of leisure riding and off-road racing, whatever their age or experience level.
In addition to the YZ65, YZ85 and YZ125 youth MX bikes and the YZ250F, YZ450F and YZ250 adult race bikes, the 2020 Off Road range also includes the PW and TTR kids’ bikes. Aimed at younger riders from 4 years upwards, the PW and TTR models are the ideal way to get into two wheels, and many of today’s champions started with one of these user-friendly models.
