What he^^^^^^ said...Yes , Common . Add gussets , use rubber washers under the flat washers . Use loctite on the bolts but don't tighten alot. Let it wiggle a bit so to speak. Try carbon fiber if you can get one.
Workshop floor could use a lick of paint tooGuys, 1250 on the clock now, here is a photo of my chain guard, might be worth checking...
Thanks Tony, I will give Norton a ring and ask if the carbon items are available... If not I'll patch it up, with gussets and rubber washer..Yes , Common .

I'll ring them and see what's available, I'll tell them the bike is newly registered and only '6 months' old see what they say...Thats came on quick, as I inspect them for cracks when I have them in for work. I raised it as a design quality inspection (dqi) when I was at Norton, but they never got around to it. I usually steered people towards a carbon replacement. Think we used to charge around £116.
Under warranty?Happened to my chrome one at around 1400 miles. Rob Jameson sent me a carbon one to replace it.
I realise that they aren't obligated as it's a different companies product. I will keep my fingers crossed for some goodwill, they did hint they would consider any problems I have.. We'll see..Well, unfortunately no SG era Norton has warranty, as that company no longer exists. Fingers crossed you get some sort of goodwill gesture, that would be a bonus! If you do get any joy with parts, would you mind updating us all? Some of us have been trying to get parts out of them for the best part of a year now.
Mine broke in the same place. I had it replaced under warranty and put a piece of rubber between the guard and the mount. That didn't work and it broke again. I then cut a piece of metal to reinforce the area that cracks and drilled and riveted it . That has held up well. I do agree with the loose tightening of the bolt and lock tite that others have mentioned.Guys, 1250 on the clock now, here is a photo of my chain guard, might be worth checking...
I've welded mine, I am hoping the bead will act as a gusset, I've also, like you put a rubber betwwen the guard and s.arm. I'll keep my fingers crossed..Mine broke in the same place.

Sounds like a good a good idea, thicker stainless sounds appealing, although maybe it'll be more prone to cracking ?As with others, mine also cracked & I fixed it by TIG welding it back together. It's probably stronger now that it was originally & so far, so good.
As it's made from a single folded piece of thin sheet steel, it did occur to me that it would be quite an easy part to have replicated by any competent laser cutting firm, who could cut it out of heaver gauge sheet, either in mild steel or stainless. Just a thought...
