One of the most debatable issues of the motorcycle is the top speed, specifically for the Malaysian model. Speedometer error on Malaysian models actually indicate that the motorcycle is going much faster than the actual speed. Testing using GPS confirmed that the speedometer shows approximately 30% higher than the actual speed, which is unusually very high.
Below is a simple table to indicate the actual speed of Malaysian's 135LC from the speedometer :
| 135LC speedometer (km/h) | 90 | 100 | 110 | 120 | 130 | 140 | 150 | 160 | 170 | 180 |
| Actual speed (km/h) | 69.4 | 77.0 | 84.8 | 92.4 | 100.2 | 107.8 | 115.6 | 123.2 | 131.0 | 138.6 |
