Gilles Tooling Factor-X Rearsets for Kawasaki Ninja 400 2018+

The exclusive, ultra-high quality Gilles Tooling rearsets are now available for your 2018+ Kawasaki Ninja 400 through TST Industries. This is a top-tier product at a competitive price.

Since these rearsets are so popular for track use, Gilles Tooling does not automatically include a rear brake microswitch in the kit, meaning that the only way to illuminate your rear brake light is by activating your front brake. To make them safer and legal for public roadway use, we recommend purchasing the Rear Brake Microswitch to provide this functionality.

If you’re looking for the lightest, strongest, and most performance-oriented rearsets available today, you’ve come to the right place.

Who says only top-tier racers should get all the good stuff? Now you can get the exact same rearsets they use for your 2018+ Kawasaki Ninja 400 and ride like a pro with the exclusive, ultra-high quality Gilles Tooling rearsets, now available from TST Industries. You can find these exact rearsets on the podiums of the Supersport and Superbike World Championships. Gilles Tooling aimed to create rearsets that would win races but could be accessible to everyone, and they rocked it. These rearsets do not automatically come with the tail light microswitch, meaning the rear brake alone will not engage the tail light by default. To make them safer and legal for public roadway use, we recommend purchasing the FXR brake microswitch to provide this functionality. Keep in mind, this will not affect the tail light actuation from the front brake in any way. If you use the front brake, or front and rear at the same time, your tail light will still illuminate with or without the use of the FXR brake microswitch. Use the Buy Together option above if you want to add the microswitch to your order and save a little cash in the process!

Only available in black.
