ADVANCED 250CC FOUR-STROKE ENGINEThe YZ250F's liquid-cooled, DOHC 4-valve, fuel-injected powerplant features a forward-positioned straight downdraft intake with symmetrical intake/exhaust ports, high-spec piston, aggressive cam profiles and reversed cylinder head layout. The advanced four-stroke engine is known for its broad, useable powerband and class-leading low-end and mid-range torque.Featuring a distinct rearward-slanted cylinder design, the YZ450F’s light, compact engine is ideally positioned within the frame for optimized weight distribution. Internally, steep valve angles allow for an even straighter down-draft intake port. More aggressive cam profiles and larger diameter exhaust header joint work together with a higher compression bridge-box-design piston, DLC-coated piston pin and longer connecting rod to churn out a broad, usable powerband, all thoughtfully packaged to provide an exceptional level of chassis balance and control. |
