Overview

This project focused on solving a known usability and durability issue with the CF-MOTO 450MT motorcycle start switch.

The original switch design is exposed and susceptible to interference from branches, debris, or external contact during off-road riding. This can lead to accidental activation or, in some cases, damage or breakage of the switch.

Using high-accuracy 3D scanning and reverse engineering techniques, a custom switch guard component was designed to protect the start button while maintaining full usability and ergonomics.

The final result is a compact, functional, and production-ready component suitable for additive manufacturing.

Challenge

The main challenge was designing a protective solution that integrates seamlessly with the existing motorcycle geometry without interfering with operation.

Key challenges included:

  • Capturing accurate geometry of the handlebar control assembly

  • Designing within tight spatial constraints

  • Ensuring full accessibility of the start switch

  • Preventing unintended contact from external objects (branches, debris)

  • Maintaining ergonomic usability for the rider

  • Creating a design suitable for 3D printing and real-world durability

solution

A purpose-built switch guard component was developed to:

  • Shield the start button from accidental contact

  • Prevent branches or objects from getting trapped in the switch

  • Maintain full accessibility and rider control

  • Integrate cleanly with the existing handlebar design

  • Be easily manufactured using 3D printing

The design balances protection with usability, ensuring the rider experience remains intuitive and unaffected.

Result

  • Improved durability and protection of the start switch

  • Reduced risk of accidental activation or damage

  • Clean, integrated design matching the motorcycle aesthetics

  • Production-ready CAD model suitable for additive manufacturing

  • Fully functional prototype validated on the physical vehicle
