Thread size for mirror ports?

vve are the end · Jul 8, 2013

I'm trying to replace my mirrors with some cheap-o's and I'm having trouble finding any adapters for the thread size I need. Anybody know what the stock thread size is off hand? I have a feeling the PO tapped these out for the weird mirrors that are currently on my bike.

I'm trying everything I can to avoid going with bar end mirrors. I'm tired of looking down so far for a rear view and I'm splitting lanes for almost 2 hours per day so I'd like to keep as much clearance as possible. Thanks for any suggestions.

10mm 1.25 pitch. You'll want to get some less than 20mm long too.

Every bike I have ever owned a bike, regardless of German, Japanese or American (I have never owned a Harley) has used M10 size threads on the mirror stalk.

Thanks guys. That's what I assumed and unfortunately mine have been tapped out much larger. They may be beyond repair so I might be stuck with bar ends.
