A Dunlop tire test to work on new products for the MotoAmerica AMA/FIM North America Road Racing Series is currently underway Thursday at Thunderhill Raceway Park, in Willows, California.

Poor weather in northern California kept all riders off track on Wednesday, but the 3.0-mile, 15-turn road course has dried out enough for testing to begin Thursday. The weather, however, remains cool with a threat of more rain at any moment.

Present at the test are:

Meen Motorsports’ Josh Herrin and Joe Roberts

Monster Energy/Graves Yamaha’s Cameron Beaubier and Josh Hayes

Team H35 Honda’s Benny Solis, Jr.

Tuned Racing’s Bryce Prince

Yamalube/Westby Racing’s Josh Day

Yamalube/Y.E.S./Graves Yamaha’s JD Beach and Garrett Gerloff

Yoshimura Suzuki’s Roger Hayden and Jake Lewis
