Description

  • RSI Billet Aluminum Momentary Engine Kill Switch – Polaris RMK / AXYS / MATRYX (Plug & Play)

    OEM Plug-and-Play Installation. Premium Billet Construction. Maximum Reliability.

    Black Anodized Finish with Laser-Etched RSI Logo

    Designed Specifically for Polaris RMK, AXYS, MATRYX & Boost Models

    The RSI Billet Aluminum Momentary Engine Kill Switch for Polaris is the premium plug-and-play solution for riders looking to upgrade the factory kill switch with a stronger, more reliable, and race-inspired design. Precision CNC machined from high-strength billet aluminum and finished in a durable black anodized coating with a laser-etched RSI logo, this switch delivers exceptional durability while adding a clean, factory-quality appearance to your handlebars.

    Unlike conventional kill switches that can be accidentally bumped during aggressive riding, the RSI switch features a momentary push-button design. Simply press and hold the button to shut off the engine. Once released, the spring-loaded button automatically returns to the run position, preventing accidental engine shutdown from tree branches, gloves, riding gear, or body movement while riding.

    This model is designed specifically for 2019-current Polaris RMK 600, 650, 850, 9R, and Boost models, while also fitting 2013-2017 Polaris Pro-Ride models and 2015-current Polaris AXYS models.

    Unlike universal switches, this version includes a factory-style OEM plug-and-play connector, allowing for a simple installation without cutting, splicing, or modifying your factory wiring harness. Simply unplug the original switch, connect the RSI switch, and you’re ready to ride.

    The compact billet housing mounts cleanly to any standard 7/8-inch handlebar, placing the kill switch within easy reach while maintaining a clean cockpit layout.

    In addition to engine shutoff, the momentary push-button design also makes this switch an excellent choice for nitrous activation, auxiliary electronics, or any application requiring a durable momentary switch.

    Designed and manufactured in the USA, the RSI Billet Momentary Kill Switch delivers professional-grade quality trusted by riders around the world.

Direct plug-in, no issues
Needed a fix for my sled and this did the trick. Feels solid and clicks positively, none of that mushy factory feel. Plugged right into the stock connector, no wiring needed. Worth the money.
