The M603 (front ) features a newly adapted mid-camber basin (casing gauge bunkers between tread blocks) that gives flexibility and plant to the tyre without dropping stiffness of the tread block
It also allows each block to adapt to the ground surface which gives an improved balance of lean grip, straight drive stability and light handling
The M604 (rear) has a redesigned broad range Supercross proven tread pattern which cuts through loose terrain to find traction and grip on a firm base
Improved grip and traction adapts to the high power and torque of the current four stroke machines
