ZETA Aluminum Free Piston for KYB AOS Forks Yamaha WR250F WR450F Kawasaki KLX450R

Description

Upgrade your off-road suspension with the ZETA Aluminum Free Piston. Designed as a replacement for the KYB AOS Twin Chamber forks, this piston is crafted from lightweight aluminum, offering superior durability compared to the stock plastic piston. It resists cracking and provides consistent suspension feel. The standard piston mimics the OE feel, while the plush version delivers a softer, smoother ride throughout the stroke. Precision engineered for Yamaha WR250F (2012-2023), WR450F (2012-2023), and Kawasaki KLX450R (2008-2019) models.
