ORIGINAL: workhorse Hi. I have been researching this can-am frame problem for some time now. The shape and number of dents in the spar greatly determines the outlanders frame reliability. Running pieces of the frame through a press shows that the frame is indeed quite strong. Especially in the stretch direction. I took sections of a slightly bent frame and ran the same press tests. Each section would have more and more puck marks, dents and scratches, and gouges from rock hopping. As you might have guessed. Even a small dent greatly weakens the outlander frame. As far as a general percentage a two inch long buy 1/8" deep dent dropped the stress resistance by about 12%. That is not a good result. I would assume that over time this would get much worse even if the remaining frame remained prestine. A full size skid plate with good mountings is a must. While the can-am single spar is strong to a certain point. They need more frame and a much more resiliant metal. I can understand the attraction to reduce weight of any object. However there is a trade off that is unaaceptable. Take for example a 400CC engine in a very light atv. If i was not tall and heavy i simply would not have enough traction to haul any trailer. No matter how good one's tires are. With 250+CC engines you certainly will not see much difference in weight if you make a single spar frame out of decent 1/4" thick steel tubing. Not to mention the less stress on the rest of the atv. I think that's the most detailed post I've ever seen for a first post
