Is motorcycle film considered a modification?

Yes
Motorcycle film is considered as modification. According to the provisions of the Road Traffic Safety Law of the People's Republic of China, no unit or individual may change the registered structure, construction or characteristics of a motor vehicle without authorization, including the body color spray and appearance structure. This means that if a motorcycle is treated with film and its original appearance is changed, it is considered a modification. Therefore, if a motorcycle owner wants to apply film, he should apply for a change of registration to the vehicle management office to ensure that the vehicle complies with the law.
