Is Adding Side Cases to a Motorcycle Considered Illegal Modification?
2 Answers
Adding side cases to a motorcycle is considered an illegal modification. Below is a detailed introduction to the scope of illegal modifications for motorcycles: Exterior modifications: Changing the vehicle's exterior logos, colors, decals, adding a sunroof, front and rear bumpers, luggage racks, rear spoilers, upgrading tires and rims, chassis, etc. Interior modifications: Modifying interior facilities, including replacing the steering wheel, installing sport seats, adding instrument devices, and sound-deadening materials, etc. Power system upgrades: Modifying components such as the exhaust pipe and turbocharger, exploiting the gap between the engine's designed power and actual power to temporarily increase displacement.
This is actually quite common. Whether adding side cases counts as illegal modification mainly depends on local regulations. I've seen cases where oversized cases or those affecting the vehicle structure got fined. Generally, certified side cases purchased through official channels are safe to install. However, unauthorized welding or altering the original design can cause problems. I recommend checking the vehicle administration website for regulations first. If unsure, consulting a professional repair shop is safer - safety should always come first, don't take risks just for convenience.
