About Us

GPS Racing is headquartered in California’s Central Valley, home of cowboys, ranchers, and some really fast motorcycle racers. Lifelong flat track fans, we grew up watching epic battles at the infamous San Jose and Sacramento Miles.

Our founder, Greg Siekierski, owns and operates a company that machines titanium implant components for the medical industry.  Over the years, he’s used his machining expertise to make parts for his own bikes.  Friends and racers noticed and asked him to make parts for them.  As requests kept increasing, Greg started sponsoring racers, building race bikes, and making more parts.

With a computer full of designs and a head full of ideas, Greg launched GPS Racing in 2015 with a mission to bring the highest quality components to the flat track community.

Some parts may look familiar, but have been redesigned to perform and fit better.  Other parts, like our Carbon Fiber Wheels, bring cutting edge technology to the flat track community. Check back often as we continue to develop new products.

Why ‘GPS’?
It has nothing to do with Global Positioning Satellites and how to find the nearest Starbucks. Here’s a hint: Greg’s middle initial is ‘P’.
