Thanks mate.
So, we had to re-desigh and find other materials to equip our alu panniers.
Things was not so easy 'cause we wanted top quality product without the prize to reach high.
And we started again the tests until we reached our goal
Pictures below is from our final result. A 42 and 35 lit set of alu panniers for my Honda Africa Twin.
Side bars is handmade also
Mounting kit (no plastic used, only some elastic parts to prevent scratches to our boxes)
And our first test
