What’s the best bike for you?

Yamaha YZ250

The Yamaha YZ250 is a two-stroke motocross bike that has been a favorite of professional riders and amateur enthusiasts for decades. This dirt bike is known for its high-performance engine, excellent handling, and durability. The YZ250 has been refined over the years and is now one of the best motocross bikes in its class. This buyer’s guide will provide you with all the information you need to know about the Yamaha YZ250, including its powertrain, handling, brakes, electronics, warranty, and updates for 2023.


The Yamaha YZ250 is powered by a liquid-cooled, two-stroke, single-cylinder engine that produces 46 horsepower. This engine is mated to a five-speed transmission that allows for quick and smooth gear changes. The YZ250 also features Yamaha’s Power Valve System (YPVS), which improves low-end torque and mid-range power delivery. This system uses a servo motor to adjust the exhaust port height, optimizing power delivery for different riding conditions.


The Yamaha YZ250 has a lightweight aluminum frame that provides excellent handling and maneuverability. The bike’s suspension system consists of a KYB Speed-Sensitive System (SSS) inverted fork and a KYB shock absorber, both of which are fully adjustable to suit different riding styles and terrain. The YZ250 also features a 270mm front disc brake and a 245mm rear disc brake, which provide excellent stopping power.


The Yamaha YZ250 does not come with any electronic rider aids, as it is a pure motocross bike designed for racing and off-road riding. However, the bike does feature a digital CDI ignition system, which provides reliable ignition timing and ensures smooth power delivery.


The Yamaha YZ250 comes with a one-year limited factory warranty that covers defects in materials and workmanship. This warranty can be extended for an additional cost.
