Fatal crashes in the US
From 2020 to 2023, 428 Ninja ZX-6R vehicles were involved in crashes on US public roads in which someone died, and 412 people died inside them. These are counts, not crash rates: a model with more cars on the road shows up more often, and people killed outside the vehicle are not counted here.
