The 2025 Yamaha YZ250X is a purpose-built off-road motorcycle designed for the rigors of cross-country racing. Its heart is a powerful 249cc two-stroke engine, tuned for enduro racing with a wide-ratio five-speed transmission, delivering strong low-end torque and a potent top-end punch. This engine is paired with a robust aluminum frame, providing a balance of rigidity and flex for optimal handling. The YZ250X also features long-travel suspension, specifically tuned for off-road conditions, with fully adjustable KYB components. Enduro-specific features like an 18-inch rear wheel, wide-ratio gearing, a side stand, and a sealed O-ring chain further enhance its off-road capabilities.
