Motorcycle manufacturers may be abandoning the 600cc sport bike class, but the folks at Dunlop are continuing to provide support to supersport riders on the track, with a new KR451 slick tire.

For those who don’t know, the Dunlop KR451 slick tire has been the spec-tire for the MotoAmerica Supersport classes, in a 180/55 R17 configuration for the rear wheel.

Choosing now to develop the race tire specifically for supersport riders, Dunlop is releasing the KR451 to fit the 5.5-inch rim used on modern supersports. This has lead to the creation of a 180/60 R17 rear tire size for the new KR451 slick – in soft and medium compounds.
