Tail light broke.

[abc]

For those of you that have used the foam backing to reinforce the tail light so that it doesn't move up and down as much... what type/size foam did you guys use for best results?

The type = high density flexible foam sheet (think wetsuit rubber type because I can't remember the name). There are pics of the mod on here somewhere - should I say s e a r c h
By "size" i assume you mean what thickness = Have a look at the gap when everything is assembled then just stick a few strips around between the gap. You probably only need an extra 1mm in thickness to give enough compressive support. If it seems to hard to compress then just reduce the surface area of the foam strips.
Dont over tighten the mounting screws and you should be ok.
Oh yeh and do what ktmguy said and epoxy around the plastic where it has proven to fail.

I just used two bits of that foam strip with adhesive on one side. Stuck it under the light on the tail tidy to support it.
Also reenforced the part that breaks off with araldite.

Good deal, I will give that a go. When I was installing the tail tidy I noticed how much the tail light moved. The tabs were ok but that much movement can't be good on a twin. Over time I'm sure the tabs will take a crap.

Here's a picture of mine.

Tail light is a replacement under warranty. I've braced it with some sort of door sealant adhesive foam, it's like 3mm thick, I put on a few layers to brace the lens and stop it from bouncing up and down, which stresses the plastic screw holders.

I used the weather strip foam on mine but still found mine broken off after this weekend's ride. I think I need something more dense as the foam I used compressed very easily. I will have to explore other options for the new one.

The only thing that works is put araldite on before you fit the new one.
I did this on the replacement I got under warranty and also when I got the new bike. I rode it home and took the rear light off and put araldite on.

Put the light mountings up.
Slightly roughen the bottom of the plastic mountings where they meet the housing with sand paper so the araldite can grip it better.
Clean.
Mix the stuff and put it round the base of the mountings. It will run down a bit and flatten out, this is fine.

Let it harden out and refit.

Hey ktmguy,

Do you mean use araldite to reinforce the actual plastic mounting lugs on the tail light ? That sounds like a pretty good idea.

Got a photo ?

Thanks

Yes, correct.

I didn't take a pic unfortunately but I might take it off and take one this weekend.

Thanks ktmguy, I wouldn't mind seeing a pic myself. But there's a part of me that just wants it to break so that KTM will have to warranty it and maybe fix it permanently if enough are reported!

[1290SDR]

Thanks KTMGuy. I will give the araldite a try. My only concern is if it breaks again before my warranty expires in September they might not replace it again if they find I have "modified" it. It is probably worth the risk. I am almost tempted to run without it and the day before the warranty ends just snap the light off and get another new one.

If it breaks again, just say you put araldite to hold it together till a new one shows up. It's not like the araldite will make it break easier....

Good call, that would work. They do not seem to sell Araldite here in the states, am I correct in assuming it is just a 2 part epoxy?

[Sarasota_Steve]

JB weld or similar.

Yes, loctite has it amongst others.

NO! JB weld is different, more for metal! Just 2 part epoxy, the stuff in the double syringe.

Went to pull my back seat to hook up the tender and sure enough, both lugs on mine are snapped. <4k miles and < 2 years old. Are you all having any luck with these getting fixed by KTM or should I go aftermarket route? Any opinions on the blaster-x tail light?

[steveberde]

Mine just broke a week or so ago after a long ride through British Columbia - I swung by the dealer on the way home. Initially he wanted to order a new light - I said whoa -
not at 250+ on me - while I was talking to the owner his son Matt went back there grabbed some longer bolts/screws and fixed it right up. If it doesn't old J B weld here I come.

First issue I've had on 14 Black

Hi all,

I know this is a year old thread but I've just found the same issue on my 2016 1290 SDR. One broken lug and the other cracked. As suggested here I'm in the process of glueing and reinforcing the lugs but was wondering if this fixed has lasted for those that tried it ?

I've checked the KTM online fiche and found that the original rear light part number has changed from 61314040000 to 61314040200. Does anyone know if this part has been changed because of this issue?

Also this new part number seems to be used on the mark 2 1290SDR which makes me wonder if there are any reports of broken lugs on the latest model ?

I'm about 3 months, 2,500 miles into the epoxy/T-nut fix- so far so good.
