Just thought i should mention, I have one of the KTMATT bashplates for my 640A.
I forgot to loctite the bolts and didn't completely torque them down (my own stupid fault) and the bashplate fell off on the highway at 100km/hr.
I ran over it, stopped, raced back and picked it up. Total damage: scratches on the base, and i made the left hand side toolbox slightly out of square. :)
Thats it! They're tough!
