 Who are we?

We are a diverse group of motorcycle enthusiasts that enjoy taking our passion to the next level.  A select few of our current members have raced or are currently racing at the professional or semi professional level, others enjoy motorcycle racing at this level only, and our most exciting prospects are the kids.  All of the kids in this organization are winners.  We strive to teach more than just riding skills, we believe that our kids are building relationships and learning lessons that will be with them a lifetime.  This sport has a funny way of teaching a child exactly what they need.  We have seen the most introverted and shy child come out of their shell with a boost in both self esteem and self confidence.  On the flip side we have also witnessed the overly aggressive extrovert receive a reality check and become much more delightful and even tempered.  In my opinion this sport offers the best of both worlds between team and individual competition. There is no doubt when the helmet goes on you are an individual, everything becomes quiet, and you realize no one is there to depend on it is just you, the bike, and the track!  When the session comes to an end and you remove the helmet you will experience a camaraderie with your fellow racers that is unattainable elsewhere.  If this sounds like something that either you or your family would benefit from then what are you waiting for contact us today @ www.omgpguy@yahoo.com !!

 Our Mission

It is the mission of the Oklahoma Mini Grand Prix to promote the sport of motorcycle road racing by offering a great learning platform for our young members as well as providing a competitive racing environment for everyone involved.          

 Special Thanks to our Sponsors

JRP

First and foremost we would like to thank JRP ownership and management for being so supportive of our sport.  JRP has been our home for many years and hopefully for many years to come.

Shep’s Yamaha/Kawasaki (Bartlesville, Oklahoma 1-918-333-4341)

The people at Shep’s Yamaha/Kawasaki have always been big supporters of the mini craze.  Many of the bikes you see racing around our track where either purchased or at the very least have benefited in some way from the R&D provided by the excellent staff.

 Moto Extreme (Broken Arrow, Oklahoma 1-918-251-6686)

Jason and Derek Owens are the brains and muscle of Moto Extreme.  Motorcycles are these guys life.  If you are looking for that unbeatable race motor or simply just need some help getting all you can out of your current set up give them a call.
