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

Made in the USA with Yoshimura’s signature craftsmanship

Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

They work! Even if you hate socks
I am not a sock wearer. Can't stand having my foot entirely shrouded in cloth. I don't wear socks with my sandals, slides, clogs and other shoes most of the year. Only on the coldest winter days. I know, It's weird. So, with my sock phobia one thing that happens is your heals get dry and rough. I opted to try these because the toes are free. I barely notice the socks on my heels/ankles when my toes get air (outside of bedcovers always). I put good thick lotion on my heels and sides of feet. A little less on the toes so they don't stain anything. The silicone lining on the heel holds that lotion against the affected areas. In a couple days my feet felt soft and looked pretty. No cracks, no white roughness. They look pink and freshly spa-ed. Fit is good on size 9 feet with thickish ankles. Highly recommend.

Nice Socks, Bad Shipping
The socks are definitely worth the price. They are cozy and non constructive. They colors are nice. My only complaint is the method in which it was shipped. Slapping a mailing label on a clear bag is not acceptable. The shipper didn't consider protecting my privacy. I hate to think if it was something extremely private. Consumers deserve better when it comes to the content of their mail.
