Highway peg mounting option. (cheap)
I recently splashed out and bought a set of highway pegs in preparation for my 23,000km trip. The one's I purchased are designed to fit on standard crash-bars, my problem was that my knees were still bent at an even more uncomfortable angle. After reviewing the many threads on what others have done I realized that the best solution was to mount them on the bash plate.
This was done by purchasing a 300mm length of all thread and two 1/2" threaded elbows and using two u bolts to attach to the bash plate. See below for the results.
My initial plan was to have the elbows pointing upwards but when I tightened the pegs the elbows moved. I will undo the U bolts and rotate the whole thing so it looks "nice". Quick ride and I am very happy with the result, $10 for the brass-ware and $16 for the stainless U Bolts.
