The RSI Racing Steering Post Pivot Adapter converts your factory flat steering post into a T-post style steering system, allowing the installation of pivot handlebar risers and oversized handlebars. Precision CNC-machined from 6061-T6 billet aluminum and finished in durable black anodizing with laser-etched RSI logos, this direct bolt-on adapter fits most Polaris RMK models—including AXYS, Matryx, PRO-RMK, and RMK Khaos—as well as all Arctic Cat models except those equipped with telescopic steering posts.
