Kawasaki motorcycles with speed limiters removed cannot pass the annual inspection. Introduction to annual inspection: The annual inspection refers to the safety inspection conducted annually or biennially on vehicles, which includes comprehensive checks on components such as horns, brakes, axle weight, chassis, ignition system, lighting system, exhaust system, and license plate installation. Annual inspection schedule: Article 16 of the Implementing Regulations of the Road Traffic Safety Law stipulates that motor vehicles must undergo safety technical inspections within specified periods from the date of registration. Passenger vehicles must be inspected once a year within the first 5 years; every 6 months after exceeding 5 years. Trucks and large/medium-sized non-operational passenger vehicles must be inspected once a year within the first 10 years; every 6 months after exceeding 10 years. Small and mini non-operational passenger vehicles must be inspected once every 2 years within the first 6 years; once a year after exceeding 6 years; every 6 months after exceeding 15 years. Motorcycles must be inspected once every 2 years within the first 4 years; once a year after exceeding 4 years.

Kawasaki motorcycles with speed limiters removed basically can't pass the annual inspection. Last time, I personally saw a fellow rider flash the ECU to remove the speed limiter, and during the annual inspection, the OBD scan immediately showed a fault code. The staff asked him to restore the factory parameters on the spot, and the emission test results also exceeded the national standard by more than double. Nowadays, the inspection cameras also verify the vehicle parameters against the registration certificate. My cousin removed the speed limiter pin and changed the sprocket, but the wheel size didn't match the factory specifications. The mechanic said that legally removing the speed limiter counts as illegal modification, and the inspection station will directly record it in their system.

Removing the speed limiter for annual inspection is really risky. My colleague's Ninja got flagged for illegal powertrain modifications after removing the top speed limit, as the engine RPM curve showed abnormalities during testing. The key issue was the vehicle's mass characteristics didn't match factory specifications, and the exhaust backpressure exceeded standards. Since last year, inspection stations have implemented a VIN traceability system that detects unauthorized ECU tuning with high accuracy. A friend at the DMV revealed that any factory-calibrated power exceeding 10% gets special attention, with some regions directly using chassis dynamometers to verify power curves.

My auto repair shop often encounters cases where speed limit removal fails the annual inspection. After the original Kawasaki catalytic converter is removed, the HC emission levels typically exceed the standard by more than double. The key issue is that tampering with the ECU triggers the write-protection counter, causing the annual OBD diagnosis to directly display 'calibration data tampering'. Last week, a customer who altered the gear ratio had a 3mm wheelbase change detected by laser rangefinders, not to mention the mismatch between the speedometer's displayed top speed and registered parameters after speed limit removal.
