Gentlemen's agreement

All major Japanese manufacturers voluntarily agreed to restrict the top speed of their motorcycles to 300 km/h (186 mph). The late 1990s saw "power wars" between various motorcycle manufacturers that culminated in Suzuki GSX1300R Hayabusa, the first production motorcycle to exceed this speed in 1999, and Kawasaki ZX-12R, designed to exceed 320 km/h (200 mph).
