The Yoshimura® Y-Series developed exclusively on Yamaha’s YZF®-R1M™ and YZF-R1 offers track-tested performance, thanks to its lineage in racing, while also being emissions-compliant*. It features a trapezoidal design, which allows for a large volume of packing material, with a straight baffle that delivers Yoshimura® Y-Series performance. The R1M/R1’s muffler front cap features MIG-welded spring hooks, while the carbon fiber end cap is riveted to the carbon fiber sleeve using stainless steel rivets and end bands.
*All claims to emissions compliance are made and supported by Yoshimura® R&D testing and documentation.
