THE FULL STORY:

The Honda CRF450R is a serious threat on the track. With their mean 449 cc, single cylinder 4-stroke engine, incredible handling, and light-weight, durable design, taking down the competition never felt so good! Honda has certainly designed a spectacular motorcycle with their CRF450R, so it's easy to see why so many riders call this bad boy home on the race track.  

When you want to take your CRF450 up a notch, install a Barkers Full Single Exhaust System! A Barkers Full Single Exhaust System will increase overall performance by increasing horsepower and torque across the entire power curve. Eliminate that sudden fall-off that occurs near redline with the stock exhaust system when you install a Barkers Full Single Exhaust System. Not only does the Barker Full Single Exhaust System weigh less than the stock exhaust, it will deliver that deep, throaty sound you've been searching for! 

 

Here is our Dyno information, provided by Alex at LaBaron's Power Sports 

These are the results for the 06 crf450r. These charts and jetting specs should be applicable to all CRF450r bikes from model year 2003-2008. Final results are as follows Green: stock pipe and jetting, Blue: Barkers exhaust with no QC and stock jetting, Red: barkers exhaust and dyno tuned jetting setup. Jetting recommendations are : 165 main jet (168 stock), 45 pilot jet (42 stock), stock needle in 5th position from top (4th stock), 100 pilot air bleed (stock), #55 leak jet (stock).


Did you look at the dyno? Did you see that unusual blip? That's from the Rekluse aftermarket clutch!

All of Barkers Exhaust Systems are hand-crafted right here in the USA from premium materials. While most other after-market exhausts are mass produced from automated assembly lines, Barker's Exhaust systems are hand-welded one-by-one by skilled craftsmen. The head pipe portion of the Full Single Exhaust System is 304 stainless steel that is Tig-welded with seam-reduced interior surfaces for smooth flow. The can is comprised of 6061-grade aircraft aluminum and comes standard in a brushed aluminum finish. For a more customized look, you may also choose to have your can powder-coated in a black or red finish. Further enhance the look of your new system by selecting which color Barker's tag you would like. Barker's tag color options include: black, blue, red or yellow. To harness your new system to your machine, a strap kit is included with your purchase.

 

At Barkers, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barker's craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials. See Barkers Terms & Conditions.

ADD-ONS:

Other options available for the Full Single Exhaust System for the Honda CRF450 machines are the Barkers Quiet Core Insert and Spark Arrestor. The Barkers Spark Arrestor will help to keep our trails safe by eliminating any flammable emissions from escaping the exhaust. The Barkers Quiet Core Insert is ideal when riding in those sound sensitive areas and will reduce sound by up 5 dB. Heck, with only a loss of .5 to 1.5 horsepower you might want to ride with them in all of the time.  

For serious riding, we highly recommend purchasing a fuel controller for your new system. A fuel controller will drastically improve the way your new exhaust system and Honda CRF450 performs. As your new system will require the added fuel flow, a fuel controller is essential for your CRF450 to perform at it’s best. For optimal results, your dealer or a skilled technician should program the fuel controller prior to installation. If you are interested in learning more about why you should purchase a fuel controller, please feel free to call us! We promise you will talk to a real person who knows all about it!

Great wrist rest. Smooth finish, good looks, and ideal wrist angle.
This wrist rest sets you up for pretty optimal, level height to prevent future wrist problems. I went with the nice reddish/brown color as it matches my brown wood Edifier speakers and other brown accessories very nicely. Nice matte finish that avoids showing finger prints and skin oils. The color is perfect, not too red or too brown. Keep in mind if your keyboard is angled in the front it will leave a bit of a gap, however it is unnoticeable to me. Also, make sure your arm rests of your chair can come high enough to meet the half inch or so thick wrist rest. My arm rests are a bit low for the time being so some extra pressure is put on my arm behind the wrist when resting on the chair supports.

Not for me
Color: Golden Oak, Size: Mouse Wrist Rest
It's tough to review something like this that functions perfectly, but just wasn't the right fit. The Glorious wrist rest for the keyboard is perfect and exactly what I wanted/needed, but the mouse rest caused hand and wrist pain. I swapped it out for a squishy alternative and that worked much better. I have a theory it might have been due to the relatively low height of my ektecity gaming mouse relative to the mouse rest. My keyboard is a higher height and that may be why the wood keyboard rest works so much better.

True-to-photos color, solid build, and great for organizing
Color: 2Pcs Green
Durability: This tray feels well-made and sturdy. I replaced a fragile tray that shattered when it fell, and this one feels like it would hold up far better to normal day-to-day handling. I am not going to stress-test it, but it feels substantial and nicely finished. Use and ease of use: It does exactly what a tray should do. It is easy to carry, stable when set down, and the woven leather surface feels secure and helps keep items from sliding around. Color: The green woven leather matches the website photos. No surprises, no weird undertones. It looks clean and high quality in person. Organization: This is where it really shines for me. It is a great fit for corralling items on a table, counter, or dresser and instantly makes things look more intentional. It is not stackable, but it is not advertised as stackable either, so that is fine. Size and accuracy: The dimensions match the schematics online, which I appreciated. It fits the space I bought it for exactly as expected. Overall, it looks high-end, feels durable, and is a simple upgrade if you want a tray that helps keep a space organized without feeling flimsy.
