The old Ninja 300 couldn’t haul itself through Euro4, so was killed off to make way for this new Ninja 400, boasting greater performance than its predecessor from an all-new engine and chassis – the net effect being a claimed weight saving of 8kg.
The 399cc engine delivers a decent 44.8bhp, its invigorated performance credited to more capacity and the new downdraft intake, which is accompanied by a larger airbox offering increased intake efficiency. While the new engine is comparable in physical size to that of the 2013-2017 Ninja 250, it’s actually 1kg lighter than the smaller displacement unit.
It also gets a new Assist & Slipper clutch, meaning much-reduced pressure at the lever for light work in town, and greater control when coming down hard through the gearbox.
Offering considerable weight savings compared to its predecessor, the new chassis is claimed to offer improved stability and manoeuvrability. The stiffer, non-adjustable 41mm (previously 37mm) fork had been developed to deliver better action, and the brake hanging off it features the latest ABS unit from Nissin, clamping down on a 310mm semi-floating disc. Star-pattern 5-spoke wheels similar to those of the Ninja 650 contribute to the weight-loss programme, while their improved lateral rigidity benefit sharper handling and cornering stability.
While the seat height of just 786mm should put the Ninja within reach of most riders, especially as the seat is now 30mm narrower, which improves stand-over.
Up at the sharp end are a pair of LED headlamps, each featuring low and high beams, as well as a LED position lamp. In the rider’s view is the same instrument cluster as the Ninja 650, contributing to the high-grade feel of the package.
The 14-litre fuel tank is claimed to deliver over 210miles of range, as the rider is cosseted behind larger-volume bodywork that is claimed to make the Ninja feel bigger than expected in the 400/250 class. It even gets the little chin spoilers at the bottom of the front cowl, just like its Ninja H2 and Ninja ZX-10R siblings.
Accessories will include a larger screen, power outlet, ERGO-FIT high seat (+30 mm), tank bag, tank pad, radiator screen, frame sliders, wheel rim tape, pillion seat cover, helmet lock and U-lock.
