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!
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, Barkers 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 Barkers tag you would like. Barkers 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.
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!
