return to their original position over time. They’re kind of
like the terminator of levers. The drivetrain of any off-road
machine is important. Tilley’s machine was equipped with
a high-tensile-strength RK X-ring chain and Supersprox
Stealth sprockets, with the rear sprocket having an aluminum inner area and a steel outer drive ring for wear life.
Dubya USA laced up a set of heavy-duty off-road wheels
using Talon billet aluminum hubs, heavy-duty spokes and
DID Dirt Star rims that could handle just about anything.
Dunlop just released the all-new Geomax 81 line of tires
specifically targeting the off-road market, so those were
mounted up. Rider comfort is essential during long races,
and ODI Controlled Flex Technology bars help absorb
impacts. Teamed with GPR’s new rubber-mounted V4 stabilizer and top triple-clamp system, they help combat rider
On the bike build side, everything went great. The engine
produced plenty of power but was easy to control and
didn’t take loads of energy to ride. Precision Concepts

For that, we will bask in a moment of glory, because it’s

the final rider crossed the finish line, one thing was certain:
Tilley was ready for a nap! The race hadn’t gone smoothly
at all. On the first lap, Tilley hit a rock embedded in a soft
berm that was the size of an elephant, sending him over
the bars, fracturing a couple of ribs and mangling the bike.
Yes, that was on the first lap! After some amazingly fast
repairs by the crew at Precision Concepts, the team, consisting of Ricky Brabec, Mark Samuels, Max Eddy, Benny
Breck and Justin Morgan, clawed its way back to second
in class and fifth overall. Tilley would ride a few more times
after his crash, but the lust for glory was gone from his
eyes, replaced by winces of pain. The team would come up
one point short of winning the overall series championship,
but no one seemed to mind. With high fives all around and
big smiles on their faces, each rider left Glen Helen with a
sense of accomplishment, mumbling, “Can’t wait till next
The controls were all about comfort and reducing fatigue
