This 4.10-18 tire features a versatile 90% on-road and 10% off-road design, making it suitable for dual-purpose motorcycles used for commuting, touring, gravel roads, and light trail riding. The IRC GP-1 combines predictable street performance with tread features that help maintain control on loose surfaces.\u003c\/p\u003e\u003cp\u003eSpecially shaped knobs penetrate loose terrain to improve traction during acceleration, braking, and cornering off the road.
