Yoshimura RS-12 Stainless Full Exhaust for Yamaha YZF 250 2024-2025

Yoshimura RS-12 Signature Series for 2024 Yamaha YZ250F

While other exhaust brands carried over systems from previous Yamaha YZ250F models into 2024, Yoshimura saw untapped potential in the new-generation YZ. Our R&D team immediately got to work fine-tuning and optimizing the system specifically for the 2024 model.

The results speak for themselves — Yoshimura’s newly developed RS-12 Signature Series full system delivers a 2.5% increase in peak horsepower and a 2.8% boost in peak torque over stock. This is exactly why Yoshimura designs, tests, and develops each system from the ground up — to unlock real performance gains.
