Offers outstanding intermediate-to-soft-terrain performance, yet its versatile design gives it a wide range of ability on harder surfaces. Shoulder knobs feature recessed biting edges for enhanced traction in ruts and flat corners. Rear tread pattern provides maximum straight-line grip for excellent starts and improved braking. Reduced tire weight produces less unsprung weight. The exact same technology we use to make full-size tires goes right into every minibike MX51.
