Dirt Bike Throttle Tubes with Precision Bearings

Experience smoother throttle control with Zero Resistance Throttle (ZRT).

Upgrade your dirt bike throttle tube with ZRT’s precision-engineered, bearing-mounted throttle technology. Designed for motocross, enduro, trail riding, and off-road racing, Zero Resistance Throttle reduces friction in the throttle assembly for smoother, more consistent throttle operation.

Unlike conventional throttle tubes that rely primarily on sliding contact between the throttle tube and handlebar, ZRT utilizes precision bearings to minimize friction and improve throttle movement.

Why Choose a Zero Resistance Throttle?

Precision Bearing Technology

ZRT throttle tubes incorporate precision bearings to reduce friction and deliver smooth throttle rotation, even during demanding riding conditions.

CNC-Machined Construction

Our throttle tubes feature precision CNC-machined aluminum components engineered for durability, accurate fitment, and consistent performance.

Improved Throttle Feel

Reducing mechanical resistance helps riders achieve smoother throttle inputs and more predictable throttle control during technical climbs, tight corners, motocross riding, and challenging enduro terrain.

Built for Serious Riders

Whether you’re competing in motocross, racing GNCC, riding technical single-track, or exploring trails, ZRT is designed to improve the feel and operation of your motorcycle’s throttle.

Find the Right Dirt Bike Throttle Tube

Zero Resistance Throttle offers fitment options for a variety of KTM, Husqvarna, and GasGas motorcycles, including select two-stroke and four-stroke models.

We also offer configurations designed for compatible wraparound handguards, commonly called Bark Busters, as well as standard motocross-style handlebar setups.

Use our Year, Make, and Model selector to find the correct ZRT throttle for your motorcycle.
