Razor MX350 4-Wire Variable Speed Throttle | Versions 1-7

Restore precision control to your ride with the Universal Parts Variable Speed Twist Grip Throttle. Specifically designed for early generations of the Razor MX350 Dirt Rocket (Versions 1–7), this 4-wire throttle allows for linear, variable acceleration rather than a simple "on/off" response. It's the perfect replacement for worn-out, sticky, or unresponsive factory grips.

• Extended Wire Length: Comes with a generous 36-inch lead, providing plenty of slack for clean routing along the handlebars and through the frame.
