Motorcycles cannot be modified before registration. Exterior modifications: Changing the body's exterior markings, color, decals, adding a sunroof, front and rear bumpers, roof racks, rear spoilers, upgrading tires and rims, chassis, etc. Interior modifications: Modifying interior facilities, including replacing the steering wheel, installing sport seats, adding instrument panels, and sound-deadening materials. Power system upgrades: Modifications to the exhaust pipe, turbo, etc., utilizing the gap between the engine's design power and actual power to increase instantaneous displacement. Other modification requirements: Changes to the body, frame, or engine can only be made if they are damaged beyond repair or have quality issues. When applying for modifications, proof from a repair shop and documentation of the origin of the replacement engine, body, or frame must be provided.

From my experience, modifying a motorcycle before licensing is quite risky. In China, vehicles must meet factory standards for registration. If you modify the engine, exhaust, or frame, it's likely to fail the vehicle inspection. I remember my neighbor had to dismantle and reinstall his modifications after failing to get his bike licensed, wasting a lot of money. Safety comes first—improper modifications can increase accident risks, such as losing control if the braking system is altered. It's best to license the vehicle first before making personalized changes or ensure the modifications comply with regulations, like minor color or appearance adjustments. This saves money and ensures safety—don’t cut corners for temporary convenience. Learn more about local traffic regulations to avoid fines on the road.

How to Repair a Dented Front Bumper?

After a car bumper gets dented, it can be repaired using the following two methods: 1. Using hot water: Most front and rear bumpers of family cars are made of special plastic materials, and hot water can help restore the dented part. The principle is that plastic softens when heated, so heating the dented area can pop it back out. Once the dent is restored, immediately cool the area that was heated with prepared cold water to allow the rubber to contract and recover. 2. Using dent repair tools: Although bumpers are highly malleable, sometimes the force from hot water expansion alone is not enough to repair the dent, so dent repair tools are needed in such cases.

What is the Difference Between High Beam, Low Beam, and Fog Lights?

Fog lights and high/low beam lights differ as follows: 1. Description one: Low beam lights are designed to provide drivers with good illumination, featuring a wide coverage area but short projection distance, with non-adjustable focus. 2. Description two: High beam lights enhance visibility and expand the field of view. On dark roads without streetlights, the visible range with high beams is significantly greater than with low beams alone. 3. Description three: Fog lights serve to make the vehicle visible to others in conditions of reduced visibility due to fog or rain. Therefore, fog light sources must have strong penetration. Most vehicles use halogen fog lights, with LED fog lights being a more advanced option.
