Description
If you’re racing soft loam or muddy tracks, tire choice directly impacts your lap times and consistency. The IRC M1A Soft MX delivers aggressive traction through its high center knobs and self-cleaning design, eliminating the mud buildup that kills grip and forces you to brake earlier. Offset shoulder knobs hold your line through aggressive turns while the extra-wide pitch keeps your contact patch working hard from lap one to the checkered flag.
