Yoshimura describes this as a USFS approved spark arrester developed specifically for RS-2 Mini mufflers. It is intended as an optional spark arrester solution for select dirt bike models and is purpose-built around the RS-2 Mini configuration.
SA-23-K is supplied as a kit to match the application. The package includes 1 x Spark Arrester Insert, 1 x End-cap collar, and 1 x Set screw, providing the key pieces needed for the spark arrester setup.
Yoshimura notes this spark arrester is designed and made in Chino California USA. As part of Yoshimura’s Replacement Service Parts lineup for the RS-2 series, it is positioned as a dedicated component for RS-2 Mini muffler owners.
Sound
Rather than a generic insert, this Yoshimura spark arrester is specifically designed for RS-2 Mini mufflers and uses the 1.550" ring configuration identified in the product name. That application-specific approach helps ensure the spark arrester components align with the muffler’s intended end-cap and collar arrangement when installed.
Installation
This is a true kit, not a single loose part. Yoshimura includes the spark arrester insert along with an end-cap collar and a set screw, which are the pieces called out for the assembly. For guidance during setup, the page includes an installation PDF link to reference while completing installation.
