    Slimline bodywork

    The YZ250 comes with a slimline bodywork that gives this legendary 2-stroke a sharp and athletic look. The narrow fuel tank and radiator shrouds give a compact riding position that enables you to shift body weight rapidly for the highest levels of cornering agility.

    Powerful braking system

    The high specification front brake set up features a 270mm diameter disc and a rigid twin-pot caliper with large diameter 25.4mm pistons that ensure optimum braking performance. A lightweight 240mm rear disc minimizes unsprung weight reduces weight while delivering instant stopping power with plenty of feel.

    High-efficiency air intake

    The YZ250’s side panels, rear fender, seat base and rear frame have all been specially developed to reduce resistance to fresh air entering the airbox to ensure optimum intake efficiency. Together with a high efficiency exhaust system this system gives you holeshot-winning acceleration and explosive power right through the rev range.

    Industry-leading KYB suspension

    Yamaha’s SSS (Speed Sensitive System) front forks are second to none. The YZ250’s industry leading suspension delivers plush low speed damping for more effective cornering performance, giving you a real advantage. Whatever the type of track, the YZ250’s sophisticated front and rear suspension makes a real difference and gives you the ability to outhandle the opposition.

    Race-bred ergonomics

    With its slim tank, narrow radiator shrouds and flat seat the YZ250 is one of the most agile handling dirt bikes. As soon as you get moving on this legendary 2-stroke you’ll find it easier to shift your bodyweight when braking, cornering or accelerating – giving you a higher degree of control.
