I LOVE their PR:

At the end of the assembly line, quality control inspectors undertake a visual inspection of the motorcycle's painted finish and fit of parts. Our quality control inspectors also feel the motorcycles with gloved hands to detect any bumps or defects in the finish. Each motorcycle is tested on a dynamometer. Inspectors accelerate the motorcycle from 0-60 mph. During the acceleration, the "dyno" tests for acceleration and braking, shifting, wheel alignment, headlight and taillight alignment and function, horn function, and exhaust emissions. The finished product must meet international standards for performance and safety. After the dyno testing, a final inspection is made for the completed motorcycle. The motorcycles are boxed in crates and shipped to customers across China and around the world.
