Motorcycle Footrest Mount Adapter for Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motorcycle footrests, such as those on the Honda Goldwing, are not adjustable and may not be optimal for riders with longer legs or those preferring a lower footrest location, limiting adjustability and compatibility with various footrest sizes and styles.
Innovation Solution
A footrest mount adapter with angled flanges that attach to the stock pivot bracket, featuring a splined pattern and internally threaded protrusion, allowing for adjustable positioning of the footrest below the stock mounting axis, enabling lower placement and compatibility with larger footrests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a stock footrest is used with an angled pivot bracket, then the footrest is retained at a fixed mounting axis level, but the footrest location cannot be lowered or adjusted for riders with longer legs or different preferences
Solution Approach 1:
A footrest adapter is introduced as an intermediary component between the stock pivot bracket and the footrest. The adapter includes a mounting body with flanges that attach to the stock bracket, and a lowered footrest mount that positions the footrest at a lower location. This intermediary device enables position adjustment without modifying the original bracket design.
Solution Approach 2:
The mounting system is segmented into separate functional components: the stock pivot bracket, the footrest adapter (mounting body with flanges), and the footrest mount. This segmentation allows the adapter to provide lowered positioning and adjustability while the stock bracket maintains its original structure and pivot functionality.
2Ease of operation
If the footrest is lowered below the stock mounting axis, then riders with longer legs can achieve optimal positioning, but the footrest may contact the ground more frequently requiring pivot capability
Solution Approach 1:
The footrest adapter maintains dynamic pivot capability through flanges with openings that receive a pin connector, allowing the footrest to pivot away from the ground when contact occurs. The spring biasing mechanism provides dynamic adjustment to maintain the footrest at the optimal lowered position while enabling movement when needed.
3Adaptability or versatility
If a fixed footrest mount is used, then the mounting structure is simple, but it does not accommodate various footrest sizes and styles
Solution Approach 1:
The footrest adapter provides universal compatibility through a splined footrest mount with an internally threaded bore that can accommodate various footrest sizes and styles. The standardized interface allows different footrest configurations while maintaining a relatively simple adapter structure.

AI summary
A footrest mount adapter includes a planar body with an upper portion and a lower portion extending at an angle relative to the upper portion. A mounting flange extends from a rear surface of the upper portion of the body for connecting the adapter to a pivot bracket on a motorcycle. The lower portion includes a footrest mount on a front surface for mounting a footrest.
