The RC-8 perch includes the legendary ARC folding/adjustable lever. The lever uses an "external pivot" that has replaceable bushings in the perch. This means NO up and down play in the lever. There is a nylon sleeve on the handlebar that helps the perch rotate in a crash preventing damage. The quick adjust is 1/8 turn and very easy to access. This perch is made from billet aluminum and CNC machined to produce a factory level assembly for the common rider. This is the exact perch that has won many national world and MXoN titles. It is available with an aluminum or composite lever.
