Dustin Robbins leads the Ultra4 USA championship on OBOR
OBOR's first Ultra4 USA season: Robbins leads 4900 UTV Open and JW Performance is top three in two classes.
Ultra4 USA National Championship
The Ultra4 USA championship combines fast desert sections and rock crawling in one race – the hardest combination for a tyre, which has to be fast and durable yet soft enough to grip rock.

In 2026 OBOR raced the full Ultra4 USA championship for the first time and is in the title fight straight away. Dustin Robbins, who already trusted the RocScraper and Tricera at King of the Hammers, leads 4900 UTV Open at mid-season.
Several teams race on OBOR. Eric Gilbert and Jason Watt's JW Performance are second overall in 4900 UTV Stock and third in 4900 UTV Modified, and Tyler Noelck, Shabs Piercy, Tony Palarie, Mitchell Rocchiccioli, Jason Washburn, Jacob Shade and Robert Liebel also race the series.
Drivers pick between the two tyres for each course: the RocScraper excels on rock, the Tricera on fast sections. The first season has shown that OBOR's UTV range can hold its own against established brands in professional off-road racing.
