TUSK Power Pull Tether Kill Switch for ATVs and Dirt Bikes — Black, 7/8" Handlebar Mount, Normally Open

The TUSK Power Pull tether kill switch is a rugged, handlebar-mounted safety cutoff that stops your ATV or dirt bike instantly when the tether is pulled.

Built for riders who need a reliable engine cutoff, this black TUSK kill switch (part# 1093920001) attaches to 7/8" handlebars with a four-bolt clamp and is wired as a normally "open" circuit that closes when the tether is pulled. It’s designed to fit a broad range of Honda and Yamaha models including Honda TRX450R (2004–2014), TRX400EX (1999–2008), 400X (2009–2014), TRX90 (1993–2025) and Yamaha Raptor 250 (2008–2013). Constructed for repeated use in off-road conditions, it gives a simple physical method to cut ignition power quickly during a fall or if you separate from the machine.

How does this tether switch mount to my handlebars?

The TUSK Power Pull fastens using a four-bolt clamp sized for 7/8" handlebars, providing a secure fit for aggressive riding. Installation requires basic tools and straightforward wiring to the ignition circuit.

• Four-bolt clamp holds the switch steady under vibration.
• Designed specifically for 7/8" (22 mm) bars common on ATVs and dirt bikes.
• Compact housing keeps controls accessible without obstructing grips.
• Mounting hardware included for a direct, repeatable install.

What does "normally open" circuit mean for this unit?

This model (1093920001) is wired as normally open, which means the electrical path is open during normal operation and closes when the tether is pulled. Closing the circuit triggers the ignition kill so the engine stops when you need it to.

• Normally open: circuit closes on tether pull, activating cutoff.
• Opposite wiring available as part number 1093920005 if your setup requires it.
• Simple two-wire hookup into the ignition or kill lead.
• Clearly marked terminals help prevent wiring errors during install.
