Gilles Tooling Factor-X Rearsets for Kawasaki Ninja 250R / 300

The exclusive, ultra-high quality Gilles Tooling rearsets are now available for your Kawasaki Ninja through TST Industries. The Factor-X Rearsets are available in standard or GP shift patterns.

Since these rearsets are so popular for track use, Gilles Tooling does not automatically include a rear brake microswitch in the package, 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 FXR 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.

The exclusive, ultra-high quality Gilles Tooling rearsets are 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. The Factor-X Rearsets are constructed of high quality aluminum and feature a durable black anodized finish. They are available in either "standard" or "GP (reverse)" shift patterns. Many riders that frequent the track prefer the GP shift pattern as it provides more ground clearance while turning, keeping your foot above the shift rod and enabling more stable upshifts while exiting corners. Since the Factor-X Rearsets are so common on the track, Gilles Tooling does not automatically include a 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.
