Convex Mirrors for Nortons?

I kept my Norton almost 100% original, and ride him a couple times a week. I have been looking for some Convex Mirrors like my Jap bike has that fit the Norton. It has 3/8-24 studs on originals. These will help the ability to see with all that awesome vibration we have! :roll:

The orbiting ellipse field of view is instead of convex :lol:

Halcyon Classic Parts in England sells a mirror head with a clamp that appears as though it would work on a stock Norton mirror stem. Here is the link:

I have a Halcyon bar end mirror myself and it is made of stainless steel and very nice quality. The mirror is convex and you can see images behind you very clearly.

If your isolastics were properly adjusted, there wouldn't be any vibration making the mirrors shake so you couldn't see behind. There should be NO vibration transmitted to the frame or the rider above 900 rpm, if the ISOS are properly adjusted.

Actually, a split mirror, 50% flat and 50% convex is a good compromise. I have mirrors like that on my 32' motorhome and they're great. Unfortunately, the ones I have are about 1.5 square feet, which aren't a big deal on a vehicle that's 8' 6" wide and 12' high. They would slow you down a bit, but I' m sure there are motorcycle-sized ones of similar configuration.

I have put on convex spot mirrors before I changed bars so easier to move head to scan danger zones. A few have installed rear video view screens, seriously. A disappearing Commando below 2000 will spoil you like the Princess and the pea. Below 1000 rpm sounds unnaturally calm. Don't bother much with isolastic tuning until both tires are in good shape and air balanced. Its educational to both under inflate and over inflate tires for enough interval to let the sense soak in permanently.

Here's some old Commando lore on mirroring isolastic details.

Looks like the Halcyon 819 would work with my arms, I want to keep my original grips, so no bar end style for me. Thank You. Now I need to try to source in the USA

I tell all of my Norton hater friends (Vincent snobs) that the mirrors on my MK3 Commando are as clear and steady at 70 MPH + as the interior mirror on any new car. If I haven't ridden the bike for awhile, it is always fun to run up to freeway speeds and verify that this still holds true. So far, so good.
None of this smooth at 2,000 rpm tho. The vibes start to disappear at 2800 and are completely gone at 3200, then it is smooth sailing right up to the red line.
At 900 rpm the whole bike shakes like an Easy Rider Harley, I thought it was supposed to?
According to the white Norton Manual, expect vibration below 3,000 rpm,and if you don't like it, the manual says "shift to a lower gear!"
This is one good reason not to gear the Commando too high, it raises the speed at which vibration disappears, hence increases the amount of vibratory riding that will occur.

Glen,
Fit a link head steady with the Mk3 spring, set the ISOs as tight as you can get away with, I set mine 0.004" front 0.002" rear, find the sweet spot on the spring the low rpm shakes will diminish and mirror wobble disappear.

must get you to adjust mine ..............................!!!
even a new one an interstate in the 70s did it they all vibrate like f...k ..
even kenny dreers

I fitted a small convex bar end mirror to the RH side of my machine - a lovely wee thing made by Oberon performance. They're pricey but superbly made and in black almost invisible looking at the bike. The thing gives a crystal clear view right up through the rev range and is very usable. My bike is a daily commuter and every so often I'll get some wag ride up behind me and try sit in my blind spot but the field of view out of these tiny mirrors is remarkable. Having said that its a shoulder check i rely on, not the mirror

Received the 819 Halcyon Mirrors. They are a perfect replacement for our Commando's. Thank You so much!
