Maxxis Maxxcross MX-SI is the soft-to-intermediate motocross tire — developed with 7x Supercross champion Jeremy McGrath. Redesigned tread and compound give superior traction across a wide range of conditions, with the rear excelling at exit traction and a new front pattern delivering lean-angle grip, predictability, and stability.
