Akrapovic Exhaust System for Yamaha XMAX 125: Performance Data and Parts List
Performance Data
This section presents the performance comparison of the Yamaha XMAX 125 with a stock exhaust system versus the Akrapovic "SLIP-ON EC-ECE" exhaust system. The data is visualized on a graph with time in seconds on the horizontal axis and wheel power (WhlPwr) and speed on the vertical axes.
Graph Description:
- X-axis: Timer1 Secnds (Time in seconds)
- Left Y-axis: WhlPwr (Wheel Power, implied units)
- Right Y-axis: Speed (implied units, likely km/h)
- Blue Line: STOCK configuration
- Red Line: SLIP-ON EC-ECE configuration (Akrapovic)
The graph indicates that the Akrapovic slip-on system provides increased wheel power and speed compared to the stock configuration. The slip-on system allows the motorcycle to reach higher speeds earlier in the time measurement and maintains performance levels more effectively. For instance, wheel power for the stock system peaks and then declines, while the Akrapovic system achieves a higher peak and sustains it longer.
