The guy that bought into LRD has a background making aluminum motorcycle frames, so he is not new to the industry. However a motorcycle frame is a whole different animal than an ATV frame.
The aluminum frames are heat treated and come anodized , so if there would be any need for welding , it would not be as straight forward as welding a Cannondale frame.
I believe the advertised weight savings is 9 lbs.
It will probably be a very good frame , but only time will tell. You got to believe that they are very serious about this project to spend all of this time and money doing R&D on a 250R frame when most all other aftermarket companies (Arens, Houser, Roll design) are doing all of there R&D on the YZF and CRF frames. I think it was a wise choice to put Bill Ballance on one of these bikes and I hope they get 1 or 2 of them into the GNC series as well.

Of course, it depends on what alloy they used and what heat treatments that they employ, if any. one thing is for certain, any aluminum frame will have a limited life when put next to a comparable engineered and manufactured steel frame. It is just a property of aluminum (no endurance limit). This is the reason why the Cannondale dirtbikes and quads are as heavy as they are (relatively). This is also why it has taken Honda so many years to refine their design. Aluminum is a different beast, and it takes awhile to get it figured out.
I only wonder if LRD did backyard engineering (like Laeger) or actual honest-to-God design work.

it’s a great idea people don’t think has anyone seen the 400ex sub frame they are so small hence tubing diameter and also the the steel frame has a stupid non existent rear bumper where the LRD ALLOWA YOU TO ADD A COOL GRAB BAR there is also metal sleeves in most of the bolt whole due to the fact that two different tallies will corrode oxidize etc
