3% peak power gains are expected when installed on a properly tuned R3 / MT-03 compared to an identical bike using OEM velocity stacks

Description

TST Industries has had a lot of Yamaha R3s over the years and collected a lot of trophies in the process. Our latest 2025 Team Yamaha Blue YZF-R3 is our first fourth-generation R3 we've been tearing into, and we've found that just like the generations before it, it can greatly benefit from some bolt-on performance upgrades. Enter our exclusive TST WORX Velocity Stacks. Through an extensive research and testing process, we determined the most effective shapes for overall power increase using the natural resonant frequencies of the R3 and MT-03 intake to develop the greatest volumetric efficiency, resulting in a 3% peak power gain and up to 8% in the top-end before the rev limiter on a properly tuned engine when compared to the same bike using OEM velocity stacks. That's enough power to help you pull away from the pack and land your race boots on the podium. No modification or special tools are required for installation, ensuring that this bolt-on upgrade can be removed and your ride returned to stock trim if needed. Our exclusive WORX Velocity Stacks are injection-molded rubber specifically chosen to withstand the harshest demands of your Yamaha race bike.

Description

TST headquarters is home to multiple R3 race bikes, and in our quest for track day domination, we have designed a simple and easy way of adding real performance and power to your Yamaha R3 / MT-03 engine. Through an extensive research and testing process, we were able to determine the most effective stack shape for overall power increase using the natural resonant frequencies of the R3 / MT-03 intake to develop the greatest volumetric efficiency. All of that work has resulted in a 5% peak power gain on a properly tuned engine 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 horsepower gains are easy to achieve and leave the ability to return to the stock setup if the need ever arises. Each R3 / MT-03 Velocity Stack is made from injection-molded rubber capable of withstanding gasoline and other harsh chemicals found in the extreme environment of your Yamaha's engine.
