Motorcycle mirror stem

thingiverse

The aftermarket mirrors installed on this bike pose some usability challenges, providing an extremely limited view of the road behind. Essentially, you mostly see your own arms while trying to navigate with these mirrors. Moreover, they allow a significant amount of vibration to seep through, which is particularly noticeable due to the V-Twin engine's inherent characteristics. A recent upgrade to printed arms/stems has significantly improved the overall viewing experience, even when idling. However, some residual vibration is still evident, although it's now much more manageable than before. Unfortunately, I won't be able to fully test this setup on the road until at least April 17th, due to the ongoing Corona virus lockdown in South Africa. It's worth noting that my bike uses M10 mirror bolts with fine threads, rather than the standard coarse thread found on most motorcycles. To secure the mirrors to their new printed arms, I opted for 35mm long cap-screws – although 40mm screws would provide an even more robust connection. By attaching extended/long nuts from the rear, I was able to effectively bolt the mirrors onto the printed arms. One final step remains: adding caps to cover the screws and complete the installation.
