Yoshimura - RS-12 Full System (KTM)

Yoshimura – RS-12 Full System (KTM)

Developed over two years of factory-level testing and refinement, the Yoshimura RS-12 Full System takes KTM performance to the next level. This system isn’t just built — it’s engineered for real gains in power, throttle response, and handling. The asymmetrical RS-12 muffler design increases internal volume for improved flow and reduced sound, while its matte carbon fiber end cap and precision-machined joints deliver a true factory finish.

The tapered muffler inlet allows Yoshimura to position the RS-12 closer to the bike’s center of gravity, improving handling and balance without sacrificing power. Combined with the patent-pending Precision Taper Fit (PTF) insert ring, insert and spark arrestor swaps are quick and frustration-free. Every component — from the welds to the fitment — shows Yoshimura’s obsession with detail and performance.

Why We Like It:
It’s the perfect mix of KTM aggression and Yoshimura precision. The RS-12 adds a deep, clean tone and instant throttle response, all wrapped in a lightweight system that looks like it came straight from the factory race truck.

Why It’ll Work for You:
This full system sharpens how your KTM feels from the moment you hit the throttle — quicker response, smoother midrange, and more controlled power all the way up top. It’s lighter than stock, looks incredible, and keeps the mass centralized for a more balanced feel on the bike. Whether you’re on the track or carving singletrack, it’ll make your KTM feel more alive.
