The modified parts industry has introduced performance evaluation standards. Modified parts are judged on four aspects: strength, compatibility, power gain, and braking efficiency. Exaggerated promotional data on modifications that endanger safety is prohibited.

To regulate the motorcycle modification market, the industry has released performance evaluation guidelines for modified parts, covering core modified components such as exhaust systems, wheels, brakes, shock absorbers, and ECUs. The evaluation indicators include: material strength of modified parts, installation matching accuracy, real data on power improvement, optimization effect of braking distance, and high-speed stability. The standards require that the original factory safety performance shall not be reduced after modification, ECU tuning shall be marked with measured horsepower and torque, and false gain promotion is prohibited. At the same time, wind resistance and strength evaluation are conducted on appearance modified parts to ensure that modification not only improves performance but also guarantees safety, helping players rationally choose compliant and high-quality modified parts.
