Z900 2026 vs 990 Duke 2026

In terms of raw performance, these two are evenly matched. The Z900 and 990 Duke produce nearly identical power figures, meaning the real-world difference will come down to gearing and torque delivery rather than peak horsepower. When it comes to agility, the 990 Duke has a clear advantage. Weighing in 23kg less than the Z900, it will feel significantly easier to handle in low-speed traffic, parking maneuvers, and twisty corners. Riders with a shorter inseam should lean towards the Z900. Its seat height is 15mm lower than the 990 Duke, making it much easier to flat-foot at stoplights and increasing confidence during stops. Bottom Line: While both are capable, the 990duke offers a superior power-to-weight ratio, making it the more exciting machine for experienced riders.
