Pro Circuit is pleased to introduce a new addition to their line of motorcycle accessories.
The Pro Circuit Pit Rug is designed to give your pit setup the “Factory” look while
protecting the ground and the environment at the same time. Adorned with Pro Circuit’s
legendary logos, this custom-crafted pit rug features a high-tech combination of
materials that quickly and easily absorb excess liquids. The tuft carpet provides
additional cushioning and comfort not found in the plastic mat versions, making this mat
“Mechanic Friendly”. The plush top also helps reduce the chance of nuts and bolts
bouncing away or getting lost in the dirt.

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.

Pro Circuit key ring / tape measure.
Total length 100cm / 39 inches

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.
