How often should a China IV motorcycle be inspected?

[HannahLynn]

China IV motorcycles require an inspection every two years when new, and then annually after four years. Below are the relevant details: China IV Standard: The China IV standard is an environmental regulation based on the Euro III standard. The higher the number, the stricter the standard, meaning vehicles emit relatively less pollution. Domestic vehicles produced between 2005-2008 generally comply with the China III standard. The China III standard refers to China's third-phase vehicle emission regulations, equivalent to the Euro III emission standard. Important Notes: If a vehicle fails to meet the Euro III emission standard due to factors like fuel quality, the OBD system will trigger an alarm and switch to default mode, rendering the engine inoperable. The vehicle must then be taken to an authorized service center for inspection and maintenance. Additionally, the OBD system cannot be retrofitted after production, so implementing the China III standard increases per-unit vehicle costs.
