Universal Parts 1" Throttle Tube

Smooth Control: Universal 1" Throttle Tube

Restore the effortless glide of your throttle with the Universal Parts 1" Throttle Tube. Specifically engineered for "Retro" and "Cruiser" style vehicles that utilize oversized 1-inch (25.5mm) handlebars, this replacement sleeve eliminates the sticking and friction caused by aged or cracked factory plastic. Whether you're refreshing a vintage-style ZNEN or a Lance touring model, this low-friction tube ensures a crisp, reliable return to idle every time you let go of the grip.

Technical Performance Features

• Oversized 1" Fitment: Precision-molded with a 25.5mm inner diameter to fit 1-inch cruiser-style handlebars (standard scooters typically use 7/8").
• Low-Friction Composite: Manufactured from high-density polyethylene for a smooth, "no-bind" rotation against the handlebar surface.
• Universal Cable Slot: Features a standard throttle cable housing point designed to accept most single-cable GY6 and retro-style throttle leads.
• Heavy-Duty Construction: Built with a 29mm outer diameter to provide a rigid, non-flexing base for your favorite 1" rubber or chrome grips.

Comprehensive Fitment Guide

This throttle tube is a standard replacement for 150cc Retro/Cruiser scooters with 1" bars, including:

Technical Specifications

• Overall Length: 146.5mm
• Inner Diameter: 25.5mm (Fits 1" Bars)
• Outer Diameter: 29mm
• Material: High-Impact Plastic

Mechanic's Note: Most scooters use 7/8" bars—this tube is significantly larger and will only fit 1-inch handlebars. Installation Tip: Before installing, clean your handlebar of all old glue and corrosion with a scotch-brite pad. Pro Tip: Apply a light film of Dry Graphite Lubricant or a tiny drop of cable lube to the handlebar surface to ensure the smoothest possible throttle action!
