Yamaha’s WR250F and WR450F enduro bikes feature some of the smartest technology in the off road world, including a unique reversed cylinder head engine design as well as the pioneering Power Tuner smartphone app that offers fast and easy trackside tuning.
The forward-facing intake and rear-exit exhaust creates a reversed layout that not only gives greater inlet efficiency for stronger engine performance – it also helps to achieve a high level of mass centralisation by locating the air intake in front of the bike, with the fuel tank positioned in the centre. The use of a rearward-slanted cylinder and wraparound exhaust also helps to centralise weight, giving extremely agile handling and lightweight manoeuvrability.
As well as their powerful and tractable engines, the WR250F and WR450F enduro bikes also benefit from an industry-leading chassis design that utilises a lightweight aluminium bilateral beam chassis with best-in-class KYB speed sensitive front forks and a link-type rear end that delivers precise and stable handling on the most hostile and challenging terrain.
For 2022 the WR250F has undergone a major engine and chassis upgrade with advanced technology from the bike that has dominated the 250cc motocross class in 2021.
So far this year the YZ250F has won both the East and West AMA 250 Supercross titles, and has taken an impressive number of victories in the MX2 World Championship and the AMA 250MX National Championship. With a more powerful engine that delivers stronger performance across the rpm range, together with a revised frame with rebalanced rigidity levels and a more powerful braking system, the new WR250F has the ability to succeed at every level.
