HDPE has about 1/3 the density of aluminium and about 1/8 that of steel so you can make it plenty thick before it gets too heavy. I've made chain sliders and guards from it. Easy to work with and can be bent permanently with some heat from a heat gun. Just can't glue it - gotta bolt it (or any mechanical fixing). Welding is possible but I haven't tested in bendy/flexy applications after welding.

Real Dakar hero with the old Dakar spirit of "do it yourself". The bike wasn't even an enduro but a MX bike.
He says that the KTM guys had been lurking his bracket. He was resigned that they were going to copy and patent it, and he would not see a single rupee.
