ZETA RACING Titanium brake disc bolt Dirt Freak DIRTFREAK D6914 model KLX250, KX250/F/X, KX450F/X, RMZ250/450…etc (old number ZT31-3724)

D6914 and old product number: ZT31-3724 are the same product. With an emphasis on workability, the head shape is designed to be different from the genuine product. Due to the superior strength of 64 titanium, we succeeded in increasing the hanging allowance of tools. *Depending on the vehicle model, some models may have the same shape for installation reasons. Additionally, some genuine disc bolts are longer than necessary, but with ZETA products, we aim to further reduce weight by changing them to the optimal length. In addition to cutting titanium parts, we also apply a hot forging manufacturing method to boast tensile strength that exceeds the strength of the material. The rolled thread is hardened by plastic deformation, so it is 1.5 times stronger than a machined thread.
