Can the motorcycle odometer be adjusted if it's inaccurate?

Motorcycle odometer can be adjusted if it's inaccurate. Precautions for motorcycle riding: Avoid racing with cars, drive safely according to traffic regulations, and yield to pedestrians. Do not follow too closely; maintain an appropriate distance by staying at the right rear corner of the vehicle in front. When overtaking, pass from the left side of the vehicle ahead; overtaking from the right or between two parallel vehicles is prohibited. Speed limits for motorcycles: On highways, motorcycles must not exceed 80 kilometers per hour. Exceeding this limit may result in penalties from traffic police. Additionally, riding without a helmet on highways will lead to being stopped and fined by the police, and carrying passengers on highways is strictly prohibited.
Having repaired motorcycles for so many years, I've found that inaccurate odometers are quite common, which can be attributed to inherent factors and acquired faults. Mechanical odometers naturally have an error margin of 5-10%, especially when the tachometer linkage gears wear out, making the inaccuracy more noticeable. For electronic odometers, issues like the displacement of the Hall sensor, demagnetization of the magnet, or moisture in the instrument panel can all cause inaccuracies. Want to adjust it? Using a decoder to alter the mileage is illegal tampering and can lead to legal consequences if caught. I recommend first checking for metal debris clogging the wheel speed sensor, using a multimeter to test the circuit continuity, and then verifying if the tire size has been changed. If it's still inaccurate, spending two hundred bucks on a used instrument panel is much safer than risking odometer tampering.
We need to be realistic about this. New cars come with an odometer error margin of ±5% from the factory, and DMV license registration accepts this range. If the error exceeds 15%, it's likely due to iron debris stuck on the wheel speed sensor or damage to the magnetic ring on the front wheel bearing. Last time, my friend's car showed 100 kilometers but only traveled 80 kilometers in reality—turned out the speed ring spacer was forgotten during tire modification. Never follow online tutorials about cutting magnetic steel wires to tamper with the odometer; that's unethical deception against the next owner. Nowadays, vehicle inspections cross-check mileage records online, and tampering will actually fail the annual inspection.
