Description

TST headquarters is home to our 2020 ASRA Moto3 National Championship winning Kawasaki Ninja 400, as well as provides support for other Ninja 400's on the track. In our quest for track day domination on Kawasaki's 399cc supersport, we designed a simple and easy way of adding real performance and power to the engine for that extra edge in performance. 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 400's intake to develop the greatest volumetric efficiency. All of that work has resulted in a 5.8% peak power horsepower gain when compared to the same bike 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 an injection-molded rubber compound capable of withstanding gasoline and other harsh chemicals found in the extreme environment of your Kawasaki Ninja 400's engine. Take advantage of hundreds of R&D hours and give your Ninja 400 some extra power with one easy installation by using our TST WORX Ninja 400 V2 Velocity Stacks.
