Bar End Mirrors Installed On A Triumph Bonneville 

If I understand your predicament correctly, all you need to do is to purchase replacement screws for the adapters in the correct size. You'll want stainless steel metric sized bolts with the correct head. if you can't find it locally you can go to Amazon and find them there.

@@tinderboxarts That might be a solution! The stock screw is a 5mm which you pointed out in your vid; the moto gadget screw on their adapters is a 6mm I believe - I’m hoping the 5mm actually expands the adapter enough to create a proper friction connection to avoid rattling. Anyway, I appreciate the response! Cheers.

You're testing my memory, but I believe the insert is either press fit by machine or welded. In other words, it isn't coming out unless you drill it out.

No, sorry. It's "baked" into the glass I'm afraid. I'm used to it now, though.

You know, I've been happy enough with the cheap mirrors. I have two bikes and my Bonnie gets used mostly on local back roads where the mirrors have less importance. No doubt the Triumph mirrors are much better quality, but their utility depends on what kind of riding you do. When I go on long trips or highway, I tend to take my sport touring bike instead.

@@tinderboxarts True enough. This is my first Triumph. Over the years I've had everything from a suzuki gt 500, first bike, to a 94 VMAX sold about 4 years ago. And several in between. No sports bikes though. I got the t100 cause I missed riding and looked sweet for a right price. The mirrors were a luxury,no doubt but just doing it as a , making it better,,thing. Don't do any long runs anymore so this is it. Last bike thing I guess. But you're right, the cheap ones did just as good, just smaller. And when you're older, better vision is a plus. Take care.

Yeah, many of them do tend to move. If you leave them alone in the "right" position they do tend to take a set there but if you start adjusting every ride they get loose.

You know, when I first put them on I thought it might be an issue, but now I don't even notice it. It's kind of like wearing sunglasses in that you don't notice them after a few minutes of wearing them. I don't do much night riding on this bike, but mirrors at night have limited utility anyway.

I've put hundreds of miles on these now. I'd probably have more, but we've had thunderstorms for two weeks straight! Anyway, I've been very satisfied. They don't rotate or move at all in the bars, and I can adjust the mirror without moving anything else. Sometimes in the garage I bump a mirror while walking past, but there's no rotation of the arm, just the mirror itself moves. I think the idea of using the existing threaded insert in the Triumph bars works great. You definitely want to tap for the larger thread, though.

tinderboxarts Thanks for the tip. May need to re-examine my install.

The place I bought these no longer offers them, but they are widely available with various brand names on ebay and amazon. Honestly, they are all probably made in the same factory, so if you just search "bar end mirrors" and pick the picture which looks right I think you'll be okay. There are also higher-end models, but these cheap mirrors have been working fine for me for several years now.

@@tinderboxartsThanks for the reply :)

Of course the field of view is smaller. The mirrors themselves are smaller and they are mounted low. However, I haven't found it to be a problem. It took me a couple of rides to get used to them and once they are adjusted correctly I can see anything I need to see. The one drawback I've found is that they tend to get knocked out of position while parked in the garage. You walk by the bike and whack the mirror with your hip, or you reach for the handlebars to move the bike and knock it out of position. I usually stop at the top of my driveway and check the mirrors now before I roll out to the street.

@@tinderboxarts hmm thanks

I can't recall what size it was, but it is metric and I did find something locally, so it isn't anything unusual. I'm pretty sure I bought a bolt too long and then just cut it down with a hacksaw and grinder.

They are M10x1.25, normal(right hand) thread types. You can also find specific mirror hole plugs.

You can find them on ebay or Amazon and probably other places too. They all probably come from the same factory but with different names attached. Whatever link I used is probably long gone now!
