I did a search and could find anything on this topic. My dad is maybe looking at selling his 07 attak GT to buy a honda goldwing, so he and my mom can go together. So if he were to do that, I would buy his sled, but I would want to extend it to a 151. I have heard the mono skid might not be able to handle all that extra length. Is this true? I know guys have extended their attaks to 144. But can it be done to a 151? Would also look into a SC after a few years, so it would need to be strong enough to stand up to 200hp. Can this be done? Or should I just hold off one more year, buy a used nitro MTX and throw a SC on that? I don't realy want to change suspentions on the attak, cost would really get high then.
