Roadrunner can you point me to this rule/spec please?Just remember seat legs have to be under plated to mot plate spec size and correct high tensile bolts used.
I want to be compliant. I have looked and looked but only find is this
and it says counter plates must be at least 40cm2 per mounting and must be a minimum thickness of either 3mm for steel or 5mm for light alloy.
which I have followed.
