4-second Kawasaki Ninja superbike donut on dry asphalt. Quick throttle rev, then high-RPM engine, aggressive tire spin, screeching, rubber skidding, throttle modulation, raw engine growl. No music or background.
A deep industrial hydraulic pump hisses, followed by metallic chain creaking for one second. Then, a sudden heavy metallic slam as a massive weight crushes a motorbike, with loud crunching thin metal, sharp headlight glass shattering, and plastic fairings snapping. Debris scatters and steel creaks as it settles. The hydraulic release occurs first, immediately followed by the impact sound with no overlap.
The aggressive spin of a motorbike wheel as it revs up for a race start.
