Pro Circuit has gotten into the Supermoto action as well.

ro Circuit has a saying, a slogan if you will, that goes like this, “We Race. We Win. You Benefit.” It’s actually pretty simple when you think about it. Pro Circuit began as a race shop and while it has developed into so much more, Pro Circuit has never left the race track. Owned and operated by Mitch Payton, Pro Circuit began as a custom precision engine and suspension building facility. Payton has invested over 25 years in engine building and machine shop techniques. Having had the privilege to work with the most talented riders in the industry has allowed Mitch and his crew to develop products and services that perform. Everything Pro Circuit makes is designed and tested at the races with only one thing in mind–performance enhancement for your motorcycle. Straight from the track to the shop and onto your bike, Pro Circuit performance products are some of the best available.
     And when Pro Circuit says they “go racing” it is not just an idle boast. Pro Circuit’s race teams have won 19 AMA Pro Racing 125cc (Lites) Number One Plates in 16 years. They began with their first 125cc Supercross/Motocross team back in 1991 with a kid named Jeremy McGrath taking the 125cc Supercross West title and Brian Swink taking the 125cc Supercross East Championship. Since then the list of riders who have won titles with Pro Circuit reads like a “Who’s Who” of racing greats. McGrath, Michael Pichon, Ricky Carmichael, Nathan Ramsey, Ivan Tedesco, Mike Brown, and Grant Langston have all won Supercross and/or Motocross Championships aboard Pro Circuit-powered machines.
     In fact, 2006 was another milestone year for Pro Circuit, as they won almost every title they went after. From Supercross to Off-Road, Pro Circuit machinery was on the track and winning races and Championships. In fact, you could say that almost every title won in 2006 was taken with Pro Circuit equipped machinery. Check out the list of riders and Championships from this year: 2006 FIM World Supercross Championship – James Stewart; 2006 AMA Supercross Championship – Ricky Carmichael; 2006 AMA Supercross Lites West Championship – Grant Langston; 2006 AMA Motocross Championship – Ricky Carmichael; 2006 AMA Motocross Lites Championship – Ryan Villopoto; 2006 Motocross des Nation – Team USA (James Stewart, Ryan Villopoto, Ivan Tedesco); 2006 US Open of Supercross – James Stewart; 2006 AMA Supermoto Championship – Jeff Ward; 2006 AMA Supermoto Lites Championship – Cassidy Anderson; 2006 Endurocross – John Dowd; 2006 BooKoo Arenacross – Josh Demuth; 2006 WORCS – Ricky Dietrich.
     Pro Circuit plans to stay on top in 2007, with a strong racing effort and new products for the consumer. Products like the Ti-4 GP System with a new end cap for lower decibel levels and a new base cap for better rigidity. For the first time ever Pro Circuit is offering a stainless (T-4) version of the titanium Ti-4 GP System design with the same improved lower decibel levels and higher rigidity. Will Pro Circuit products help your customers win races? Their race record speaks for itself!
