What is faster a kx65 or a kx500?

The KX500 is significantly faster than the KX65 due to its larger engine displacement and power output. The KX500 is a high-performance Motocross bike with a powerful 500cc two-stroke engine, while the KX65 is designed for younger or less experienced riders with a smaller 65cc engine. This difference in engine size and power translates to much higher top speeds and acceleration for the KX500.
