In the modern era, 400cc machines remain an excellent midway point between the 250cc and 600cc classes, but many do not offer the same performance and thrill as their older counterparts. However, the arrival of the new Ninja ZX-4R ushers in a screaming 400cc revolution with an all-new In-Line Four engine making an unprecedented 57 kW (77 PS). Winding it up, the tachometer climbs to over 15,000 rpm to produce an intoxicating wail that is music to the ears of high-performance motorcycle fans—a clear audible signal that the Ninja ZX-4R stands apart in the 400cc class.
