RIDER: David Burton
AGE: 20
HOMETOWN: Columbia City, Ind.
CLASS: GNCC 20+ C class

1651627_HWmugDavid Burton competes in the C-class ranks in the Grand National Cross Country racing series. To ensure he has a good shot at improving in his second year and hopefully challenge for the podium, this young kid from Columbia City, Ind., has built himself a full-blown A-level quad with a-tough-guy attitude.

Why would a C-class rider need such a highly modified quad, you ask?

“Being in the Indy Dealer Show was something I had thought about doing in the past. Towards the end of the 2007 season, I decided I wanted to try a different suspension setup. After researching, ARS-FX was the setup I was after. With everything being so expensive I came up with the idea to show my quad in Indy. After some great advice from my buddy Ben Wrightsman, I was on my way. What started out as a few companies ended up with 21 helping,” Burton said.

1651627_HotwheelspipeBurton has been riding quads for around 8 years and has raced them for a few, but still considers himself a newbie in the GNCC ranks. He attended only seven events last year and still earned 12th in the 20+ C class.
He said the prize parts on his Honda are the all-new ARS-FX EXIT X2 shocks built by Michael Hallock, the Precision stabilizer, Flexx bars and TireBalls. Obviously, all these parts are designed to reduce rider fatigue and produce a better handling quad.

1651627_HWengineYou may not think good power is something a C-class racer needs, but Burton says it’s the opposite. He believes if you learn to master the woods with more horsepower and a responsive engine, it makes you a better rider in the long run. He said Moto-Xperts took care of the mill, porting and polishing it, adding a three-angle valve job and reshaping the combustion chamber. Those changes along with a Baldwin XC cam, HMF exhaust and a Moto-Xperts-tuned carb, his Honda is dialed.

1651627_HWrearAnother key component is the Rekluse Z-start Pro clutch. Throw in a modified tranny (Moto-Xperts, again), and this 450R is a breeze to ride. Burton doesn’t have to worry about becoming a clutch master with this combination installed.

To ensure the chassis holds up to GNCC abuse, BK Performance gusseted and powder coated the naked chassis.

Burton says he would not have been able to construct his dream quad without help from friends and family.

1651627_HWrightengine“A local mechanic, Jason Orr from Orr Motorsports has been a gigantic help and it would be hard to have made it this far without him,” he explained. “ I would also like to thank my parents, Toby from Moto-Xperts, Tyler Moore, Shawn Nash and all the great companies that helped.
