The Michelin® Starcross® Sand 4 tire was developed for sandy tracks like Southwick, where conventional tires struggle for traction and cornering grip at extreme lean angles. The scoop-like knob placement of Starcross® Sand 4 tires helps provide excellent traction without digging in. Already a proven winner at the legendary Le Touquet beach race, Starcross® Sand 4 tires are available in two rear sizes for all current motocross bikes.
