I mentioned in another thread the mod I have done to my 2013 rear mudguard attachment to reduce breakages. Thought it better to make a new thread rather than hijack the suspension repair one.

I drilled a couple of small holes in the guard and put a couple of washers and a spacer sleeve onto the bolt that connects the inner guard, tank and muffler at the rear of the bike. I then take a cable tie and pass it through the holes, over the top of the guard then down beneath the bolt. Now when I flip the bike the cable tie breaks instead of the guard.

I found a 5mm cable tie was a bit strong and 2mm a bit weak. I've settled on 2mm for now. I carry several spares poked through the handlebar pad attachment points.

I've used a soldering iron and a piece of the plastic cut from the rib under the guard (visible in photo) to repair a couple of cracks caused before this mod.

 

I use the plastic number plate bolts, I weaken them with a Stanley knife.

They work (and break) a treat
