I bought this new from Luxon and used it for about 5 hours. Does a nice job taking out the harshness of the shock during high speed compression. Take note of the scrape in the pic from crossing a log. Bearings are obviously excellent and greased. I’ll put the description of the knuckle from Luxon below along with a link to their site. Should fit 23-24 KTM and Husky linkage big bikes and 24 GasGas linkage big bikes but see the website to confirm. “ Our high performance linkage knuckle addresses the shortcomings of the KTM/Husqvarna/GasGas rear suspension. The corrected motion ratio of the rear suspension delivers increased traction, bottoming resistance, and predictable handling.” https://www.luxonmx.com/product-luxon-ktm-husqvarna-gasgas-23-suspension-knuckle-n2d.html
