RSI Billet Aluminum Momentary Engine Kill Switch – Ski-Doo Gen 4, Gen 5 & Lynx Radien (2 stroke engines only)

The RSI Billet Aluminum Momentary Engine Kill Switch is designed specifically for Ski-Doo Gen 4, Gen 5, and Lynx Radien models. Precision CNC machined from billet aluminum with a durable black anodized finish, this spring-loaded momentary switch requires a simple push-and-hold to shut off the engine, preventing accidental shutdown while riding. It includes OEM terminal pins pre-crimped to the wiring for installation into your factory connector housing. No wire cutting or splicing is required, although the factory connector must be opened and the terminals repinned during installation.

RSI Billet Aluminum Momentary Engine Kill Switch – Ski-Doo Gen 4, Gen 5 & Lynx Radien

Premium Billet Construction. Factory Fit. Race-Proven Reliability.

Black Anodized Finish with Laser-Etched RSI Logo

Designed Specifically for Ski-Doo Gen 4, Gen 5 & Lynx Radien Models

The RSI Billet Aluminum Momentary Engine Kill Switch for Ski-Doo Gen 4, Gen 5, and Lynx Radien models is the ultimate upgrade for riders looking to improve the durability, appearance, and reliability of their factory kill switch. Precision CNC machined from high-strength billet aluminum and finished in a durable black anodized coating with a laser-etched RSI logo, this premium switch delivers exceptional performance while giving your handlebars a clean, factory-quality appearance.

Unlike conventional kill switches that can accidentally be 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, eliminating the possibility of accidentally shutting off your sled from gloves, riding gear, tree branches, or body movement while riding.

Designed specifically for Ski-Doo Gen 4, Ski-Doo Gen 5, and Lynx Radien platforms, this model utilizes OEM-style terminal pins that are professionally pre-crimped onto the switch wiring for a clean, factory-quality installation.

Unlike a direct plug-and-play connector, installation requires opening the factory electrical connector housing, removing the original terminal pins, and inserting the supplied RSI terminals into the OEM connector body.

No wire cutting or splicing is required, but basic depinning and repinning of the factory connector is necessary during installation.

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