TST WORX V2 Velocity Stacks 18-23 Kawasaki Ninja 400/Z400

TST WORX V2 Velocity Stacks 18-23 Kawasaki Ninja 400/Z400

TST made waves in the Ninja 400 racing scene with our 2020 ASRA Moto3 National Championship winning machine, and we aim to do the same with our new 2024 Kawasaki Ninja 500. By adapting the technology that we developed on the Ninja 400 platform to the updated Ninja 500, we've unlocked hidden performance that can provide the edge you need to win the race. Through an extensive research and testing process, we were able to determine the most effective velocity stack lengths for overall power increase using the natural resonant frequencies of the Ninja's intake to develop the greatest volumetric efficiency. All of that work has resulted in a 7.69% peak power horsepower gain when compared to the same Ninja 500 using OEM velocity stacks. That's a significant performance boost that can help you land your race boots on the podium. Installation is an easy bolt-on process, which means that real-world power gains are easy to achieve and leave the ability to return to the stock setup if the need ever arises. Each Velocity Stack set is made from a chemical-resistant compound capable of withstanding gasoline and other harsh chemicals found in the extreme environment of your Kawasaki Ninja 500's engine.

Features
