In the never ending pursuit to craft the very best exhaust system, Yoshimura introduces the latest titanium RS-12 system for the 2023 Honda CRF450R.

Why did they go through the task of introducing a whole new system for the CRF450? With the latest engine spec, the engineers wanted to get the best most usable power from this new model. 

This new system has been developed with and is the closest thing to what 5x World Champion Tim Gajser, Mitch Evans, Ken Roczen and Chase Sexton have been using to grab holeshots and win races. By increasing the resonator in the RS-12 muffler by 50cc (a 14% increase) and adding a second resonator to the header, engineers were able to unlock some insane usable power from this new and improved system.

What does this translate to?

  • Easier power delivery
  • Smoother frontside torque
  • Allows the rider to ride in an higher gear, thus freeing up suspension.
  • Less rider fatigue
  • Made with the premium grade Japanese titanium tubing, this new system adds 5% max hp and 6.5% max torque to the new engine spec with its smaller throttle body and different ECU settings.

The RS-12 proudly developed, designed, and made in the USA.

So Helpful for Dry Mouth Relief
⭐⭐⭐⭐⭐ This Moisturizing Mouth Spray in Gentle Mint has been perfect for my mom, who struggles with dry mouth due to Sjögren’s. It provides quick moisture and feels soothing without being overpowering. The mint flavor is light and gentle, not too strong or artificial, which makes it comfortable to use throughout the day. The spray is easy to carry and convenient for on-the-go relief. Overall, this has been a very helpful product for managing dryness and improving comfort. We’re really pleased with how well it works. ⭐⭐⭐⭐⭐
