The asymmetrical muffler configuration maximizes packing volume to ensure sustained performance. Specifically for international customers, the T-5 Euro System meets the FIM 2 meter max sound requirements.

Used by the Monster Energy/Pro Circuit/Kawasaki Race Team, the Pro Circuit Shift Lever is now available to the public for the first time. The new shift lever is CNC machined from billet 6061-T6511 Aluminum and hard anodized with stainless steel spring and hardware, making it stronger than a stock part and more able to resist wear, bending and corrosion.

The free-folding, knurled shift tip is replaceable and completely rebuildable. In addition, this design helps prevent dirt from clogging and interfering with the shift lever functionality. All shift levers come with bolt for installation.

*Made in the U.S.A.
*Machined from CNC billet aluminum
*Free folding, knurled shift tip

Used by the Monster Energy/Pro Circuit/Kawasaki Race Team, the Pro Circuit Carbon Fiber Chain Guide combines precision, performance, and style-The Pro Circuit Carbon Fiber Chain Guide includes a Carbon Fiber Chain Guide Bracket, as well as a Chain Guide Block Insert. The Bracket extends farther towards the rear wheel than an OEM bracket, allowing the drive chain to feed directly from the chain guide to the sprocket, providing a precise feed of the drive chain to the rear sprocket. The high-quality carbon fiber materials and machine-finished profile earn the Bracket a few more style points than what is available out of the crate.

The Pro Circuit Carbon Fiber Chain Guide also comes with a Chain Guide Block Insert. The Insert is CNC machined from high-density polyethylene, providing a durable, long wearing, and low friction surface for the chain to ride. The Insert fits tightly within the Bracket, reducing the clearance between the chain, guide block, and sprocket. This also contributes to a more direct and precise feed of the drive chain to the rear sprocket, reducing the likelihood of chain derailment. The Insert also wraps around the front face of the Bracket to provide wear protection to the Bracket. The Insert can also be purchased on its own as a replacement part, if needed, giving you more for your money.

Pro Circuit Carbon Fiber Chain Guide:
· Made in the U.S.A.
· Currently available for KX 250F/450F 2009-12 models
· Kit comes with Carbon Fiber Chain Guide Bracket and Block Insert
· Provides a precise feed of the drive chain to the rear sprocket
· Chain Guide Bracket extends farther towards rear wheel than OEM bracket
· Chain Guide Block Insert is CNC machined from high-density polyethylene plastic

Kawasaki Linkage Arm
The Kawasaki Linkage Arm was designed to stiffen up the initial part of the linkage curve and lower the chasis, making the bike much more stable. This will also help eliminate the initial loose and wallowy feel. Turning and cornering capabilities are greatly improved as well.
And although having your suspension revalved by Pro Circuit would make a considerable improvement, the Linkage Arms alone provide a major improvement over the stock set up. *2009 KX250F Length is the same as stock, so there is no performance gain over stock, the only improvement would be the strong billet aluminum material.

Made for most current Kawasaki and Yamaha Models.

Winner of our strangest call-in question: The guy who wanted to know what sizes our umbrellas came in. People: it's an umbrella. Pro Circuit being based in Southern California, almost every weekend they are out there somewhere else...and lots of times it rains. If they can figure out how to win that many #1 plates over the years....we can figure out how to get out of the rain. This is the umbrella they use.

Provides plenty of leverage and keeps springs from shooting all the way across the garage! Perfect addition to any toolbox.

Made from lightweight aluminum and designed to hang from your toolbox for quick and easy access to your complete set of t-handle tools.

Designed to sit on the lip of your toolbox for easy access and holds all 7 of you T-handles.

The Pro Circuit Keychain/Taper measure is probably the absolutely most highly prized item in the MX/SX world. Here's why: guys buy this keychain. Then they have their hair dyed red, an ortho makes them shorter by removing spinal discs, then they top it off with plastic surgery. End result: they look just like Ryan Villopoto. After a race, they go to a bar, toss the Pro Circuit Keychain on the counter...chicks fight over who gets to be first...and well....you know the rest.
