Kawasaki Ninja 400 STG Project Bike

  • The 2018 Kawasaki Ninja 400 is the latest lightweight bike to hit the market so we decided to pick one up and do another STG Project Bike. A lot of moto media outlets are labeling this an "entry level" motorcycle which is fair given it's displacement and super comfy ergonomics. While we agree this would be one heck of a first bike we also feel the current crop of lightweights are a ton of fun to ride no matter your experience level. The Yamaha R3 has become pretty popular with experienced track riders since it was introduced in 2015 because it has proven to be a ton of fun to ride and the price is very affordable.

    With the Ninja 400 we will focus on street mods for the first part of the 2018 summer season installing all the bolt ons we can get our hands on. Once we finish the street mods we will turn the 400 into a track bike and begin the second part of the project.

2018 Kawasaki Ninja 400 M4 Slip On Exhaust Install

  • We love this bike but the stock exhaust is too quiet, too heavy and it is just plain ugly. Installing the M4 Kawasaki Ninja 400 2018 Carbon Slip On Exhaust is a project most any rider can tackle and get a great result. The M4 Slip On for the Ninja 400 features a carbon can with a carbon end cap that really cleans up the look of the bike. M4 ships this system with the quiet inert installed and we feel the performance of the bike is best with the insert in place.

    M4 did a great job on this slip on and we feel it is a good buy at just over $400 with the carbon can.

2018 Kawasaki Ninja 400 M4 Full Exhaust System Install

  • If you want to get the most power out of your Ninja 400 then a full exhaust system is a must. M4 worked hard to make what they feel is the best full system on the market today for the 400. Installing the M4 Kawasaki Ninja 400 2018 Carbon Full Exhaust System requires a little more effort than installing a slip on, but it is a project most can manage with common hand tools. Kawasaki did a great job making the OEM bodywork on this bike easy to remove and reinstall which makes projects like this one a whole lot easier. This system can be installed using the stock passenger pegs or the race mount bracket M4 includes with the system.

How To Remove The Stock Bodywork on a 2018 Kawasaki Ninja 400

  • OEM bodywork removal and re-installation has not gotten any easier over the years. As the technology has moved forward on the bikes the bodywork has become more difficult to work with on most models. I am happy to report the 2018 Kawasaki Ninja 400 is not included in the group of bikes with over complicated OEM plastics. Kawasaki did a great job with the OEM bodywork on this bike, it is easy to get off and reinstall which makes both maintenance and mods a whole lot easier to do. In this video we cover how to remove and reinstall the OEM plastics on the Ninja, focusing on the right and left side fairings. The tail section is pretty straight forward and we will cover the upper fairing when we do our race bodywork installs.

2018 Kawasaki Ninja 400 Spiegler Brake Line Kit Install

  • Replacing the stock rubber brake lines with stainless steel braided brake lines is the best bang for the buck performance mod you can do to your bike. Doing this will increase both braking power and feel at the lever making the bike even more fun to ride. Installing the Spiegler Kawasaki Ninja 400 2018 ABS Front & Rear Brake Line Kit on the bike requires reasonable mechanical ability and common hand tools. In this video we show you what it takes to get this done every step of the way if you decide to tackle the project yourself. If you watch this video and do not feel comfortable with the project we recommend taking the bike to a licensed motorcycle technician.

    ABS equipped motorcycles require a little more patience and finesse when installing brake line kits as compared to their non ABS counterparts do, still this is worth the effort. Bleeding the brakes on an ABS bike is no different than a standard model, just takes a little longer to do with the additional line length.

2018 Kawasaki Ninja 400 Akrapovic Carbon Slip On Exhaust Install

  • Akrapovic produces some of the highest quality products in the world today, no one will argue that. The Akrapovic Kawasaki Ninja 400 2018 Carbon Slip-On Exhaust is everything we expected it to be before we began the install. The carbon canister comes with a noise reducing insert presintalled to keep the noise in check. This is removable if you choose to do so and we had Max Van rev the STG Ninja 400 with and without the insert installed.

    This Carbon slip on is designed to be easily upgraded to a full system by installing the Akrapovic Kawasaki Ninja 400 2018 Stainless Steel Optional Header if you prefer to replace the entire system from cylinder head back. We will have a video install for both the Akra Header and this slip on very soon.

2018 Kawasaki Ninja 400 Driven Fender Eliminator Install

  • If you have seen our STG Best Sportbike Mods Feature you already know we did not start this project with Mod #1, the Fender Eliminator. We finally removed that boat anchor of a stock rear fender and installed the Driven Kawasaki Ninja 400 2018 Fender Eliminator w/Arrow Turn Signals on the bike. The Driven Fender Eliminators serve up a pretty unique design that uses all machined billet aluminum pieces. With the Driven kit you have the option of getting one with or without turn signals. They also just released the Driven D-Light LED Plate Frame we install in this video which is a slick finishing touch for sure.

    Replacing the stock rear turn signals with the Driven LED signals we also needed to replace the turn signal flasher to get the proper flash rate on the Ninja 400. If you are cool with the flash rate being much faster than OEM you could leave it as is.

2018 Kawasaki Ninja 400 Driven Axle Block Sliders Install

  • The Driven Kawasaki Ninja 400 2018 Axle Block Sliders look great on the bike while protecting that swingarm. These replace the thin sheet metal OEM axle adjusters with machined billet aluminum goodness available in several colors to personalize your Ninja 400. We went with red on our STG Ninja 400 Project Bike which meet heavy protest from Max Van who felt blue would have been the way to go.

2018 Kawasaki Ninja 400 Driven D-Axis Grips Install

  • You don't have to do a whole lot of riding before you discover that the OEM grips really suck. Replacing the grips with a quality set of aftermarket grips can make it more comfortable to ride and dress it up a bike. We really like the Driven D-Axis Grips because they use a 2-ply gel grip that feels great in your hands (reduces vibration a bit as well) with colored accents on both ends to get that pop of color. This is a quality grip that we have ridden with quite a bit here at STG so we know it performs great and lasts a long time.
