Equip Your 2019 YZ250F and 2019 KX450 With a Stronger Part


CORONA, CA - April 11, 2019 - Pro Circuit has recently released new clutch covers for the 2019 YZ250F and the 2019 KX450 models. Pro Circuit clutch covers are CNC-machined from T-6 billet aircraft-grade aluminum to improve durability and heat dissipation. Cooler operating temperatures means improved performance. Here's your chance to add a product to your YZF or KX machine that is stronger, lighter and will also add a works look that the OEM cover never could.
