A Bashplate is made to protect the engine WTF do you want to start protecting the suspension and footpegs etc 
'cause that's what gets damaged on the DR650 on a regular basis. At least on my seven DR's. Footpeg bracket bolts smashed flat to the point where a socket won't fit or bent are not the exception but the rule.
And do yourself a favour and check for the prices of the nedle bearings in the suspension lever. They will get ruined once the seal has been hit by a stone and bent. Not to talk about a full hit on the front of the lever when going over a curb (like the one at Kriges

) or a rock.
I built these on instructions and design form some DR riders
This is what they wanted --and this is what i gave them--At HALF the price.
I assume "at half the price" is aimed at my bashplates?
Well. you don't have to get your panties into a knot just because I don't like your plates. I have stated clearly why I don't like yours and you are more than welcome to criticise my design.
I am well prepared to explain every little detail of it

I build bash plates to combine a reasonably high level of protection with low weight and value for money. This is what
I wanted. A few others liked the design and others again found out about its advantages. No one so far complained about paying too much.
Want something to your own spec--give me the design and i will build anything you want--even if i do NOT like the design--You have money to blow--i will gladly take it 
You see that's where I'm different. If I think it's crap I tell you and I will not waste my time on it.
Fark if you start bending frame rails you will
1) need more than 3-4mm of alu protection
2) get off a DR and buy a RMZ

The frame "rails" of the DR650SE are actually tubes and it does not take much to damage them. I have seen it happen more than once on my various DR's. The sump can actually take much more abuse than the frame cradle. This is due to the fact that the frame tubes are more exposed and vulnerable thanks to their design, shape and wall thickness whilst the cast aluminium of the sump can absorb and dissipate quite an impact without suffering structural damage.
3mm aluminium sheet is well enough to protect the DR's frame cradle from the worst:
You just have to take the right aluminium - not the one they use to make tin foil from

and you have to know how to shape it and how to attach it to the bike to make sure it can dissipate an impact
