Yoshimura - RS-12 Full System (Yamaha)

Yoshimura – RS-12 Full System (Yamaha)

After more than two years of factory-level development and race testing, the Yoshimura RS-12 Full System brings pure championship DNA straight to your Yamaha. Every detail was built for performance — from the aggressive asymmetrical muffler design that increases volume and flow, to the matte carbon fiber end cap and precision-machined joints that make this system both functional and beautiful.

The RS-12 was engineered for maximum gains in power, throttle response, and durability. Its tapered inlet design moves the system closer to the bike’s center of gravity, improving handling and balance. The result? A system that adds power while trimming weight and giving your Yamaha that deep, tuned Yoshimura tone. The patent-pending Precision Taper Fit (PTF) insert ring makes swapping out inserts or spark arrestors quick and simple — no frustration, no struggle, just track-ready performance and pro-level refinement.

Why We Like It:
It’s everything a Yoshimura system should be — race-proven, lightweight, and flawless in both sound and craftsmanship. The carbon fiber end cap, tight welds, and sculpted lines make it look factory fresh, while the tone and power feel straight off the Supercross circuit.

Why It’ll Work for You:
This system makes your Yamaha feel stronger everywhere — quicker throttle pickup, smoother pull, and noticeably better response through the revs. The improved weight balance helps the bike feel lighter and more stable, while the carbon cap and titanium finish add that unmistakable Yosh look. It’s plug-and-play performance that transforms how your bike rides and sounds.
