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.

Variants / Options:
Includes full stainless header and mid-pipe assembly. Compatible with Yoshimura repack kits, sound inserts, and spark arrestors (sold separately).

Key Features:

  • Developed and race-tested for over 24 months by Yoshimura’s factory team

  • Asymmetrical RS-12 muffler design increases power and volume

  • Carbon fiber end cap with inset decal and precision-machined joints

  • Tapered inlet improves mass centralization and fitment

  • Patent-pending PTF insert ring for easy sound insert or arrestor changes

  • Improved throttle response and mid-top power gains

  • Lighter than stock (8.5 lbs. vs 8.7 lbs.)

Made in the USA with Yoshimura’s signature craftsmanship

Very firm and durable
Color: Cool Grey, Size: 24x24x12 inch
worked great for husbands surgery recovery. Very affordable, firmness was great, looked nice on the bed and also used it for the grandkids when they were watching a movie. Moved around with ease. Didn't use it to sleep with all night though. He could only make it half the night but that wasn't the pillows fault. It was the cast on his arm. Definitely did its purpose after surgery and the need to sit up in bed more. highly recommend

Perfect. I used it when I was recovering from hip surgery. Relieved a lot of pain in my hip and knee at a time when I needed relief.

this pillow is huge i’m 5’8 and it’s perfect, as soon as i laid down it relived pressure in my back, i get hot fast and you can feel the cooling silk like texture, it’s weighted aswell, as soon as i opened it, it fluffed up an it’s been about 2 hours since and it’s already huge, it says 24-48 hrs to fluff up fully but idk how much bigger it could get lol it’s definitely worth the few extra dollars

I must have for pregnant women! Definitely helps sleep and comfort for sleeping!!
Size: 57 Inch, Color: Light Grey, Size: 57 Inch, Color: Light Grey
I do love this pillow, it does take up a lot of space on my queen bed! But when I wrap my legs around the pillow, it gives me much relief on my back! It also has basically a built-in pillow so you don’t even need to use a pillow! I love that I was able to unzip the outer material and wash it! You can use it to sit up and support your back, and when the baby comes, you can use to help with feeding! sometimes I have to turn it completely on the other side if I want to turn over, it’s big!! heavy! Very soft! Not flat at all! Firmness is great! Height is great! I highly recommend! I’m also five months! i got it about 2 months ago!!

Buy this one!
Size: 65 Inch, Color: Light Grey
This was a great buy! I looked through many many different options before buying and this one was the one I chose. Definitely a good choice. It keeps its shape and is cool to the touch which is amazing for a hot sleeper. It helps so much with my sore hips being 7 months pregnant. Fits great on my queen size bed with room still got my partner to sleep comfortably as well. Definitely recommend!
