The Yamaha YZ250, an iconic motocross machine, has reigned supreme as a benchmark in the two-stroke motocross world for over a decade. The 2004-2008 iteration of this legendary bike pushed the limits even further, delivering an unparalleled combination of power, agility, and control that cemented its status as the ultimate weapon on the dirt track.
### **ENGINE**
At the heart of the YZ250 lies a screaming 249cc, liquid-cooled, two-stroke single-cylinder powerplant. This high-revving engine cranks out a blistering 50 horsepower, effortlessly propelling the bike forward with explosive acceleration. The Power Valve System (YPVS) ensures optimal power delivery throughout the rev range, providing a smooth and linear surge of torque that keeps the rider in the powerband at all times.
### **CHASSIS**
The YZ250's lightweight aluminum frame is the epitome of rigidity and agility. Its advanced geometry and suspension system provide exceptional handling and stability, allowing riders to push the limits with confidence. The 48mm inverted front forks and Monoshock rear suspension offer fully adjustable settings, empowering riders to fine-tune the bike to their specific riding style and track conditions.
### **SUSPENSION**
The fully adjustable 48mm KYB inverted front forks with air-oil separation provide exceptional damping performance and front-end feel. The damping settings can be tailored for varying terrain and riding styles, ensuring optimal handling and control in all conditions.
### **BRAKES**
Powerful dual-piston calipers grip 270mm front and 245mm rear petal-type discs, delivering exceptional stopping power and feel. The progressive brake lever and pedal modulation allow riders to control the braking force precisely, ensuring maximum cornering and braking performance.
### **HANDLING**
The YZ250's razor-sharp handling is attributed to its ultra-responsive chassis and suspension system. The lightweight aluminum frame and advanced geometry ensure nimble cornering and precision steering, while the fully adjustable suspension allows for a customized setup to match the rider's weight, riding style, and track conditions.
