Yoshimura RS-12 Exhaust System | 2024 Kawasaki KX450
Спорт
The 2024 Kawasaki KX450 has been well received in terms of its handling and overall ride-ability, but the power output has been a point of disinterest for many so far. Check out our review of the RS-12 Yoshimura system aboard the new green machine.
Performance gains are massive with our RS-12 Signature Series system, adding a whopping 23.8% max hp and an incredible 16.4% max torque.
The RS-12 muffler has loads of features including our PTF insert system that makes changing inserts a breeze and an optimized muffler shape with added volume and brake caliper clearance.
Yoshimura's RS-12 systems are designed, developed, and manufactured in Chino, California.
Rubber mounted RS-12 muffler dampens vibration to subframe.
Aggressive intelligently designed, the RS-12 asymmetrical shaped muffler allows maximize capacity and incorporates a resonance chamber for managing sound and increasing usable power. RS-12's unique profile also provides more clearance for tire and brake caliper.
Improved performance gains with refined power delivery.
Just like the works systems our Factory Racers use, RS-12 systems utilize precision machined joints. Machined joints provide a superior and exacting fit for joints by better securing the seal between two surfaces with a perfect 360 degree contact surface which translates into improved system life, fit and performance.
New patent pending Precision Taper Fit (PTF) insert ring makes it easy to install and remove sound inserts and spark arresters.
Works-look matte carbon fiber end cap with industry leading design, innovation and detailing as expected from Yoshimura.
Carbon end cap covers the RS-12 inner cap, thus improving looks, while providing easier service as compared to other sandwich mounting designs most commonly found in the industry.
Repack Kits, optional Inserts and Spark Arresters are available for all models

They sure love a long ass muffler on the kx450
ML can you tell us how this Yoshimura compares to the pro circuit system?
Love the green look
Hello, thanks for the video. Can I put this on my new 24 450x with out doing any other modifications, with this pipe or the pro circuit.Is there a bid difference between the two. I plan on drilling extra holes in the airbox under the seat and battery area, plus I already removed that rubber piece under the battery. I'm trying not to do any ECU or mapping adjustments yet. Ride single track only., thanks john.
What's going on with testers doing 350 vs 450 test and favoring the 350, then talking down on a lower power 450 if the higher power isn't better for their test riders?

450 has more inertia so a low power 450 can feel heavy

as always they are trying to sell a product. They also say how great the chassis is.. until a new one comes out next year then it will suck.

@@gdsvfrWe've seen this story play out before... A few years down the road and these same journalists / reviewers will be saying that Kawasaki took a step backwards from the 2019 - 2023 generation, when the design was changed in 2024
Does this review account for an aftermarket ECU?
How did this pipe compare to the pro circuit

would like to know the same.
450 that you can push versus have to manage and you’re complaining 🤦🏻♂️
