Yamaha XMAX 125 Performance and Parts
Performance Comparison
The performance graph displays the results of a dynamometer test for the Yamaha XMAX 125. It compares the stock exhaust system with a slip-on exhaust system (labeled SLIP-ON EC-ECE). The horizontal axis represents time in seconds (Timer1 Secnds), measured using a SuperFlow WinDyn™ V system. The left vertical axis shows Wheel Horsepower (WhlPwr) in units of approximately 0.5 WhlPwr per grid line, ranging from 7.0 to 11.0. The right vertical axis shows Speed, ranging from 30 to 100. The blue line represents the 'STOCK' configuration, showing a gradual increase in WhlPwr and Speed. The red line represents the 'SLIP-ON EC-ECE' configuration, which shows a higher WhlPwr and Speed curve compared to the stock system, particularly at higher engine speeds.
