Comprehensive Fitment Guide

This rear wheel is a universal replacement for many 33cc, 36cc, and 43cc 2-stroke gas scooters, including:

Technical Specifications

• Tire Size: 9x3.5-4 (Tube Type)
• Sprocket: 55 Tooth (#25H Chain)
• Bearing Size: 6000 (10mm ID)
• Hub Width: 120mm

Mechanic's Note: This assembly is specifically setup for a Band Brake. If you are replacing a wheel that originally used a disc brake, this will not be a direct swap. Always verify your axle diameter (10mm) and chain size (#25H) before ordering, as these "stand-up" scooters often used several different drivetrain configurations in the same production year.
