  • Relocates the easily damaged OEM voltage regulator
  • Mounts to the TST Frame Slider mounting bracket
  • Requires some drilling and rerouting of wires during install
  • Great for racing applications
  • Drastically cheaper than other relocation solutions on the market
  • Used on our in-house TST Ninja 400 Supersport race bike


The stock placement of the voltage regulator places the unit in an extremely vulnerable position, allowing it to be easily damaged even in a mild crash. In our racing efforts with the Ninja 400, we quickly saw a need to relocate the rectifier and keep it in a more protected area without spending a ton of cash or adding unnecessary weight with a dedicated bracket. Using our TST Frame Slider mounting bracket, this kit moves the stock regulator to the back of the frame slider bracket and secures it with stainless hardware, adding protection for a small price and an even smaller impact on your bikes overall weight. You will need to drill mounting holes into the TST Frame Slider mounting bracket, but it's an easy install that any racer can quickly tackle. Don't overpay for what can be a simple and cheap solution to keeping your Kawasaki Ninja 400's voltage regulator safe in the harshest racing conditions.

Q: Can I mount these without the TST Frame Sliders?
A: No - we specifically designed this to work with our Frame Slider mounting bracket, therefore they are required for proper installation and relocation of your OEM voltage regulator.

Q: Do I have to do any drilling?
A: Yes - you will need to drill mounting holes into the TST Frame Slider mounting bracket as well as reroute some wires.

Q: Is it sturdy?
A: Very - Since this uses the Frame Slider mounting bracket as the backbone to the installation, you gain added protection to your regulator that many other brands can't offer.

Q: How long will it take for me to receive this once I order it?
A: Please see the articles in our support center regarding domestic and international shipping.

Q: I'm located outside of the United States. Will I have to pay duties on this item?
A: Some countries charge additional fees when a package is imported and delivered to the recipient. We have no way of knowing or estimating what these fees will be. It is the buyer's responsibility to cover these additional costs.

Q: What is your return and warranty policy?
A: Please read over our policies thoroughly on our terms and conditions page BEFORE making your purchase.
