TUSK Tether Kill Switch for ATV — Black Power Pull, 7/8" Clamp, 4-Bolt Mount, Compatible with Honda & Yamaha

The TUSK Power Pull tether kill switch is a handlebar-mounted safety cutoff that instantly kills the engine when the rider is separated from the machine.

Designed for ATVs and youth quads, this black TUSK kill switch provides a compact, reliable way to stop the engine during a fall or emergency. Built with a four-bolt mount and a 7/8" clamp diameter, the unit installs on common ATV handlebars and works with multiple Honda and Yamaha models. This particular part (1093920001) is a normally open circuit that closes when the tether is pulled—if you need the opposite behavior, TUSK offers part 1093920005.

How does the kill switch protect riders during a fall?

When the tether is attached to the rider and tensioned, the switch completes or interrupts the ignition circuit so the engine will immediately stop if the rider is thrown from the machine. It reduces the risk of runaway ATVs and lowers the chance of secondary injury from a still-running vehicle.

• Immediate engine shutdown when tether is pulled
• Simple mechanical action that doesn’t rely on software
• Visible mount keeps tether orientation predictable
• Works with both youth and adult riders when installed correctly

Will this TUSK switch fit my handlebars and ATV model?

The switch clamps to 7/8" handlebars using a four-bolt bracket, a common size on many sport and trail ATVs. It’s listed as compatible with several Honda TRX and Yamaha Raptor and 400X models—verify your model year and wiring before buying to ensure correct hookup.

• 7/8" clamping diameter fits standard ATV handlebars
• Four-bolt mount provides stable, vibration-resistant attachment
• Compatible with Honda TRX450R, TRX400EX, TRX90 ranges and Yamaha Raptor 250 models listed
• Part number 1093920001 is normally open; check if you require normally closed

How hard is it to install and wire the kill switch?

Installation is straightforward for basic wiring: mount the bracket on the handlebars, route the wires to the ignition, and splice or connect following your vehicle’s wiring diagram. If you’re not comfortable with electrical work, a quick shop install will ensure correct polarity and safe routing of the tether cord.

• Mounts with four bolts for secure positioning
• Wiring connects into the ignition/kill circuit—follow vehicle schematic
• Tether attaches to rider clothing or belt for quick release
• Professional installation recommended if unfamiliar with ATV wiring

What durability and performance can I expect from this switch?

TUSK products are engineered for off-road use, and this kill switch is built to withstand vibration, dirt, and regular impacts. The black finish resists corrosion and the mechanical contact design offers long-term reliability without dependency on electronics.

• Rugged housing tolerates dirt and moisture exposure
• Mechanical switch design minimizes electronic failure modes
• Four-bolt clamp resists loosening from rough terrain
• Replaceable tether and simple mechanical action for easy maintenance

Who is this for: Riders who want a durable, easy-to-install safety cutoff for sport and trail ATVs—especially owners of compatible Honda TRX and Yamaha Raptor/400X models. This kill switch is ideal for riders who prioritize quick engine shutdown after a dismount, racers and recreational riders who want added safety, and anyone replacing a worn or non-functioning tether switch. Confirm your vehicle’s wiring and whether a normally open or normally closed circuit is required before purchase.
