OEM 48mm WP AER forks removed from a 2018 350SXF with 31.8 hours total time. These forks are in very good condition with light signs of use. There is no evidence of leakage on either fork leg. These forks have been revalved by Marshall's in 2020. I do not know the specifics of the valving. All of the lower guard attach bolt holes are in good condition, as are the forks in general. Upper clamping surface is 54mm, lower clamping surface is 60mm. These forks use a 22mm front axle which is used on many bikes from 2015 on. I did not disassemble these forks. My evaluation is based on a visual inspection only. Please confirm that you bike uses a 22mm axle prior to purchase.
