Finding a mono-style BMW R100 final drive isn’t the hardest task, but tracking down one with a specific ratio is getting more difficult these days…
•
I managed to source this one from the other side of Canada, thanks to

While everything looks good on the outside, I still want to verify that it’s within spec and go through it with a full internal overhaul
•
Here’s a quick look at how I confirm the ratio before tearing into it

The 1970’s BMW headlight bucket may look simple from the outside, but there is more going on beneath the surface than meets the eye.
•
One detail I focused on was the twin fuse holder, which is typically glued inside the bucket. While exact placement is not critical, I wanted to refine this area with a more intentional design.
•
An integrated internal feature now precisely locates and secures the fuse holder, allowing it to be glued in place without the risk of shifting while it cures.
•
For those looking to stay closer to an OEM style setup, the fuse holder will also be offered as an optional accessory once the headlight bucket becomes available.
•
Working on the small details now before I reveal the final product to you. More updates coming soon!

I need your help. I’m currently looking for a Mono Final Drive for my custom R100 project. The following ratios are of interest:
•34/11
•33/11
•32/11
The last image is for reference purposes only.
•
By adding a mono swingarm, it changes the overall look of the bike while also opening the door for further modifications.
•
The final drive will be modified along with the rear wheel.
•
This will also tie into the frame, which requires some work now that the swingarm contacts the upper frame brace. In that area, the frame can be reinforced and reshaped to suit a custom suspension setup.
