Arrow competition exhaust systems for Kawasaki Ninja 400

Arrow competition exhaust systems for Kawasaki Ninja 400


One of the most recent trend of the motorcycles manufacturers is to reduce the cc of bike models already on the market under 500 cc to reach a bigger audience. Kawasaki Ninja 400  is the latest development in small displacement spot bike industry, but has immediately become the spearhead for the WSS300 class (consecrated to small displacement bikes, in which only riders from 15 years old onwards can race), in both national and WSS300 championships.

Exhibit for the first time at the Tokyo Motor Show, after 10 years form first Kawasaki Ninja model (the 250 cc) appearance on the market, this bike is light and easy to ride hence perfect for riders with little experience. The Arrow full system can make this bike even more performant.

Competition and Competition Evo Arrow full systems are the result of a collaboration with top-level teams and are the best option for racetrack-tuned bikes, for both national and international championships and amateur or track races. Their great performances have been proved by the first place of Ana Carrasco at Imola (DS Junior Team) and the second place of Borja Sanchez (ETG Racing Team), both riding a Ninja 400 with an Arrow Full System on the WSS300 championship.

What is the difference between Competition and Competition EVO full system?
Let’s start by saying what they have in common. The Competition and the Competition Evo full systems have the same 2:1:1 collector scheme and the same silencer. Moreover, they both are in compliance with the national and international regulations for noise pollution and are made with top quality material, such as titanium and carbon.

Below the features for each full system.
• Competition full system has been designed to be used on bikes with a lower level of tuning and these can work well also on standard engines, prodiving to make some modifications on ECU settings, either with a change to OE maps or by installing a separate ECU module. Competition systems can be installed with OE radiator and bodywork and so these can be quite taken as “plug-and-play” systems, providing to make the upgrades on electronics settings described before
• Competition EVO system, instead, is designed with different solutions and features (i.e.: crossover pipes between collectors) to fit engines tuned (both electronically and mechanically) at an higher step. Dimensions are reduced to give more clearance to bigger race radiators or to additional ones, something well fitting to Ninja 400 design and that allows to use race footrests and race bodywork. To allow the use of special racing ECUs, EVO systems come with an M18 plug for oxygen sensor and so it is necessary to remove or disconnect OE ECU and oxygen sensor.
