Is your throttle sticking, binding, or feeling inconsistent on your vintage Honda CB400? After decades of use, the original plastic throttle tubes often become brittle, warped, or cracked, leading to poor throttle return and an overall sloppy feel — but there’s now a clean, modern replacement designed to fix that.
This 3D-printed replacement throttle tube is designed specifically for 1978–1980 Honda CB400A (Hondamatic) and CB400T models. It directly replaces the factory tube while maintaining the correct geometry for smooth operation with stock handlebars and factory-style grips.
Manufactured from rigid, impact-resistant white ABS plastic, this throttle tube offers improved strength, dimensional stability, and longevity compared to aging OEM plastic. The result is a smooth, consistent throttle action that eliminates sticking, binding, and lag caused by worn original parts.
This kit includes:
🟩 (1) ABS throttle tube
Key features & benefits:
🟩 Direct-fit replacement for 1978–1980 Honda CB400A and CB400T 🟩 Rigid, impact-resistant ABS construction 🟩 Eliminates sticky or binding throttle behavior 🟩 Restores smooth, predictable throttle response 🟩 Compatible with factory handlebars and grips
Whether you’re refreshing a survivor bike or correcting an annoying throttle issue on a daily rider, this throttle tube delivers a simple, durable fix that restores proper feel and control.
Professionally designed and tested by Incendiary Concepts LLC, with vintage Honda ergonomics, reliability, and performance in mind.
