Yamaha' s YZ450F is one the bikes that seems to win the accolades of media testers of almost every level. We set out to make an even better experience with big blue.

It's no secret that the YZ450F has tons of power and torque, so we focused on smoothing the transition of both. Our new RS-12 responded perfectly, maximizing mid / top power and torque to boot! With the power transition smoothed out the YZ450F has more connectivity to the dirt, enabling you to focus on other things...like winning!

Available in durable stainless steel with an iconic aluminum muffler, our new RS-12 Signature Series exhaust system is the best exhaust system for the YZ450F hands down.

NEW YZ450F RS-12 Features and benefits

  • 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.
  • Tapered muffler body inlet design of RS-12 enables the system to be pushed forward thus helping with weight centralization without sacrificing performance.
  • 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.
  • Proudly designed, developed and made in the USA!
  • Repack Kits, optional Inserts and Spark Arresters are available for all models

Far superior to price comparable Sony receiver
Set name: 5.1 Receiver
I want to compare this to Sony STRDH590, which I owned before this and is of a comparable price. My Sony stopped receiving signal from its remote control within 2 years. There was no way to control many features due to this. The Yamaha has a wide range of buttons on the front if the remote fails. Now that I have this Yamaha and can compare the sound, this is MUCH better than the Sony. The sound is crisp and clear. This Yamaha receiver has a 5ch stereo expansion setting and the Sony did not even have that. This receiver also has a direct setting that turns off all extra parts of the stereo to attempt to get a clearer signal, including the front panel. The Sony has the nicer input ports (the ones that take the banana plugs) only on the left and right channel where this Yamaha has them for all five channels. The subwoofer output from the Yamaha is considerably better than the Sony and produces a cleaner sound. The Yamaha setup is extremely easy and takes just a few minutes with the included microphone. So far I haven't had too much difficulty with voices being quiet in movies. There are several applicable sound options for how to process movie input. The only downsides to this Yamaha are that it only has 4 HDMI inputs and doesn't support eARC. According to the marking ARC is only on the first HDMI input.

Excellent sound and function
Set name: 5.1 Receiver
We're very pleased with this unit. We use a 3.1 system in our TV area, stereo plus center channel and subwoofer. It's nice that this unit supports that. We get very nice imaging from this, and don't really miss the surround speakers. **We had to replace the old HDMI cables with new ones that could handle the larger bandwidth of 4K. If you're cables are 5-10 years old like ours, newer cables are required to carry a modern video signal. We like the Yamaha sound, and are able to EQ it easily to sound right for the room. I've used several receivers over the years of various brands. Yamaha consistently delivers good sound and reliable product. I've never had a Yamaha product fail and fewer than 15 years. There are other units out there with more gadgets and gizmos, bills and whistles, not to mention smoke and mirrors. We want a good sounding reliable unit that plays nice with all of our AV sources and TVs. If that's what you're looking for, look no further than this unit right here. If you get a good price on this, it's unbeatable. Sony, Onkyo, Denon, Marantz, etc. - they all make good units with signature sounds. If you aren't familiar with them, and If you can't listen to a bunch of stuff, buy this with confidence. Here's an unsolicited recommendation: high quality speakers will do more to improve your listening experience than any receiver. If you're looking for an upgrade, start with your front speakers.

Love my Yamahas
Set name: 5.1 Receiver
RX 385 replaces my much-loved 10 year old RX 375, which I inadvertently fried while experimenting. The 385 has some newer features, including bluetooth. The old model and this both use the handy YPAO function to tune the audio speakers' depth of field to the listening environment. It's a broadcast mic that you just plug into the front of the receiver for a few seconds to determine each speakers' distance from viewer. Kind of a sonic echo measurement of seating to speaker. It's a foolproof, remarkably clever, timesaving gizmo. The YPAO mic is absolutely included with this unit, looks like a little plastic cone. Also important to me, Yamaha has replaced the old spring clips for rear/side speakers, which are now the better screw and cap posts, as they have always been for the two front speakers. I recommend rocketfish HDMI 4k/8k cables to connect this receiver to your tv and to whatever other components you want, such as a bluray. Sound quality is excellent if your speakers are good. (I like KEFs.) Of course you may prefer wireless speakers, but I'm already committed to wired ones. I used rocktfish banana plugs to connect my speaker wires to the RX 385 receiver's speaker posts. Neat and clean. With a choice of 2 front, 2 rear, 1 center speaker, plus one coaxial plug in for a subwoofer, your movies and programs are going to sound far more detailed and staged than you'd get from the tv or a sound bar. It's a more immersive and compelling experience. (I use only 2 fronts and 2 rears and don't feel I'm missing anything.) Yamaha receivers and other components are my favorites: relatively inexpensive, well designed, solidly built, and not fussy to install. If you find yourself in a pickle there are a couple of helpful youtube videos. I find with the RX385 again that Yamaha does not disappoint me.

Outstand Product!! 😉
Color: 14AWG-1 Lead
This is my second (at least) Nilight wiring harness. I wanted to re-do the lights on my Rhino 660. This makes it SO EASY! 👍🏼😉 And a hell-of-a-deal!! All I had to get was a "reamer" drill bit to enlarge the switch holes on my dash. Run the wire, attach the ends to the light, switch & power source, all done. I did add "shrink tubing" to my connections to add an extra layer of insulation/weatherproofing. 👍🏼
