Lower chain guard
 

Does anyone know where I can get a lower chain guard from?
I got a steel upper chain guard and a thicker chain and sprockets (525). But I'm still worried to death of that ****** bouncing off.

Would be nice to have one...
but the chain will need to be pretty lose for it to de-rail...

I have had one bad experience and I have read several accounts on here.

35 odd years rideing and 34 bikes... never had a chain come off...
Have broken 2... IT465 & 1100 Katana at a drag meet..
Sorry... more of a owner issue than a bike issue...

Edit.... now I think about it... i have had a chain de-rail
speedway bike... but that was a owner issue...
In a hurry doing a gearing change between races... didn't re-adjust it..

Lower chain guard
 

Good point, my incident was down to my own ignorance and was indeed my fault. Although most of the dirt bikes around me do have lower chain guards so there is some reason for concern, as riding in the conditions I do, I think the possibility is somewhat increased and the likely hood is not just based on mechanics, the conditions in which we ride clearly has some bearing..

I do regularly Adjust mine but the value in terms of peace of mind is worth it for me.

Sorry, but it is more an issue of having a chain guard or not, so it's a bike issue.
I hadn't a derailed chain on my bike too. But every bike I owned had a chain guard. So rethink if any of your bikes had no chain guard. Your IT465 had one for example. A Katana 1100 doesn't need one. It's a road bike. IMHO a chain guard is compulsory for a trail bike. That's why most of them have one.

Guys fit a ktm guide. There's been threads on it before. Simply put. ,.... Remove central bush. Cut guide in half. Slip over chain. Make bracket and fit to swingarm.

Found one thread although looks like you've got to be some sort of genius to make it.
Can't believe there is no third party company making these

The most difficult will be to bore and thread the swingarm in the right place. That would not improve event with a third party kit ..

Surely a simple clamp around and swing arm would do
