BATTLECROSS X31 (NHS) 90/100-21 57M TT Tube Type Front Bias Motocross Off-road Motorcycle

[Bridgestone MCS01573 Battlecross X31 (NHS) 90/100-21 57M TT Tube Type Front Bias Motocross Off-road Motorcycle Tire]
・The BATTLECROSS X31 is a tire that achieves high off-road performance on medium to soft surfaces.
・With the BATTLECROSS X31, "Castle Block," previously only used on the rear tire to ensure ground contact, is now also adopted on the front tire, improving grip.
・On soft ground, the tire sinks deeply into the soil, and the groove area around the blocks also comes into contact with the soil. By placing bunkers (indentations in the tread) at the bottom of the grooves on both the front and rear tires, when the bottom of the grooves contacts the soil, the edges of the bunkers dig into the soil, providing high off-road performance on medium to soft surfaces.
・Bunkers reduce the rigidity of the tread surface, making it easier for the surrounding blocks to follow the road surface, which also improves ground contact stability.
