Starcross® HP4 tires are designed for hardpacked, extreme "blue-groove" conditions. Starcross® HP4 tires feature innovative knob patterns designed to help maximize cornering traction on hardpack. The wide 90/100-21 front Starcross® HP4 tire (as opposed to the typical 80/100-21 size) provides a larger contact patch that enhances predictability in blue groove conditions. The taller, wider front casing also provides greater air volume for absorbing hard landings.
Sand 4 Rubber mixture is designed to perform well even in cooler temperatures. Designed for low infl ation pressures-can be used as low as 12 psi. Specific knob pattern for 125 2-stroke and 250 4-stroke increases float to avoid power loss. For use with S12 or MS3 front tires
