TST WORX Velocity Stacks 2025 Yamaha R3 / MT-03

TST WORX Velocity Stacks 2025 Yamaha R3 / MT-03

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.

Features:

• Provides 3% increase in peak power, and as much as 8% increase in top-end power before the rev limiter
  
• Supersport legal in CCS and ASRA
  
• Simple and easy installation that does not require any special tools
  
• No modification required for installation
  
• Injection-molded rubber construction is chemical-resistant to withstand gasoline and other harsh chemicals
  
• Developed through extensive research and testing by the TST Industries WORX Racing Program
  
• Should be paired with TST WORX Airbox Cover and TST Stage 2 Tune for best results - see WORX Pack for complete bundle
  

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