[Anti-Degradation Fin]
Anti-Degradation Fin ? (Adopted on rear of X30/X40)
Motocross tires used at low internal pressure is grip-down occurs in the heat generated by the repetition of the sidewall bending. Therefore, in order to suppress heat generation, the cooling fin which is the run flat tire technology for passenger cars was improved for motocross tires and arranged on the side wall. This will cool the tire with running wind and suppress grip down due to heat generation.
[Castle Block]
Castle Block ? (Convex Block) (Adopted on the rear of X20/X30/X40)
It is very slippery that the road surface is like a floating on hard soil, or just after watering at the race intervals. It adopts "Castle Block" which jumped out from the usual block surface in order to secure firm grip even under such as circumstances. It improved grip power compared to conventional products by improving ground contact pressure on slippery road surface.
•It optimizes block rigidity according to muddy road surface
•Low Profile Block
It placed a low block in the center as in the current M102
It becomes the resistance of mud flow in the tire width direction, suppressing side slip.
It secures mud clearance by making the height lower than the normal block.
