Yamaha Yz450f 2018 year models

For 2018 Yamaha made some major refinements to the already potent YZ450F. Adding to the usable and tractable power is how we make the new YZ450F even better. Now there can be more power to rip holeshots, yet making the bike user friendly at the end of the moto when your right hand gets a little frisky.

The work that went into developing the RS-4 muffler has paid big dividends in Off-road Racing; winning multiple Supercross and Motocross titles since it's inception. We've developed the current generation RS-4 based on that research & development, and the result is a unique design that provides an unrivaled combination of power and quiet exhaust tone. The RS-4 features a Polyresonant duplex chamber and two-staged stepped baffle for increased performance, while a carbon cone end cap finishes off its innovative styling.

  • Pentagonal-shaped sleeve
  • Front muffler cap functions as a polyresonant chamber which helps reduce noise
  • Two-stage stepped baffle
  • Carbon fiber end-cap
  • Stainless steel tail-pipe
  • Repack Kits, optional Inserts are available for all models

Note: Installation of a new exhaust system may change your motorcycles fuel-air mixture requirements. Please consult the manufacturer directly with questions regarding any modifications that may need to be made during, or after installing their product. If a jet kit or EFI controller is recommended please see the Intake/Fuel section for products available

Note: Exhaust discoloration (bluing) is caused by engine conditions such as cam timing, fuel-air mixture, operating temperature, etc. It is not the result of defective manufacturing; therefore it is not covered by any warranty. See the Chems/Lubes section for products to help remove or prevent exhaust discoloration
