I would sure hate to be a Vince or Larry crash test dummy for BMW. I rode a new production GS last year and it had a tendency to get a bit of head shake at times. It was very strange feeling and even if I had liked the bike I would not buy one if it did that. I just brushed it off thinking it was the way it was set up for the demo rides. It was set as low as it could go and soft as it could go. Not sure if correct set up for me would have eliminated that or not. It is interesting reading about Kevin Ash and makes you wonder what happened there. I do not know what type of aluminum that frame is made out of on the BMW or even how it is made. I have not seen one but with these big bikes steel or aluminum if they are rode like yz 125's they are going to break. I see all those pro riders doing amazing things on those big bikes and actually in the video I watched of the T7 I could see the swing arm and frame flexing. Of course those people riding the Africa twins and KTMs and Yamaha's or what ever it is are not using those every day like I would and don't even care if they can ride it tomorrow or not. As far as welding the aluminum sure a tig welder with the right rod is always going to be best to control the heat and material in the weld but over the years between me my buddies and then all the kids we have welded several swing arms and a couple frames with a Lincoln electric buzz box and aluminum rods and have done very well with them. Some of it was extruded aluminum and some areas were cast but got the job done. We even welded an aluminum wheel back together and sort of got it semi straight! haha. Of course that was all play bike stuff and they were in the woods low speed stuff 40 mph or lower. I am not sure i would want to do that on a big bike. Guess if i was in another country and they could do it why not. Take it easy and get on to the next place.
