From my years of experience in understanding vehicle regulations, installing motorcycle crash bars may not necessarily be considered illegal modification. The key lies in compliance with local laws and vehicle safety standards. For example, in China, the "Motor Vehicle Registration Regulations" stipulate that any modification must not alter the original factory structure or performance parameters of the vehicle. If the crash bars are well-designed, do not obstruct lights or signals, do not affect braking or riding posture, and have been inspected and recorded by professional institutions, they are generally legal. However, many regions require prior declaration of changes to the vehicle management office; otherwise, unauthorized installation may result in penalties and even affect annual inspections and insurance claims. I recommend thoroughly researching the rules of the local traffic management department before installation and choosing qualified safety products. Illegal modifications can lead to fines and penalty points, and more seriously, endanger others' safety. From a broader perspective, any vehicle modification should prioritize safety enhancement rather than just aiming for a cool appearance. I have personally witnessed many riders overlook details such as bolt tightness, leading to accidents. Therefore, what may seem like a minor issue is actually significant and must be handled with caution.
