Marvin Musquin won the 450SX Main Event in Seattle but has failed to make up championship ground after he was penalised points.

Cooper Webb has kept his 14 point lead in the rider standings thanks to Musquin failing to keep his wheels grounded for a medical flag in Seattle.

Early in the Main Event a collision that involved Justin Brayton and Chad Reed brought out the medical flag. Musquin didn’t keep his wheels on the ground, which is in violation of the rules.

The Frenchman kept his win but was penalised seven points – Webb continues to look in good shape for the 450SX championship.
