2019 RM-Z 250 sees a new era and with the partnership of JGR Factory Suzuki Racing we were able to develop the very best option for the new RM-Z 250
For Yoshimura, the heart of performance and power is our RS-4 muffler with its Polyresonant Duplex front chamber, special baffle and added overall volume helps make the 2019 RM-Z250 come alive. All designed around making power that the new Zook puts out to be most efficient.
If you're serious - it's only Yoshimura. Proudly made in the USA!
