for the money you could try it but on a mx race two weeks ago i saw one of the top riders brake one leg because of one like this... after a small fall on a turn he fastly pick his bike and some sinutes later, on a big jump, the footpeg broke.
I picked up a set for my kdx, my xt350 and my friends dr350. they are great pegs I would not worry about breakage as my friend (280lbs) has beat his dr350 for over 2 years with these pegs.. jumping crashing sliding the bike on its side on pavement.
I have used them on my kdx and after many get offs they are still staight and are in great shape 2 yrs of use.
My xt 350 is a daily rider and part time off road bike ...same thing no problems.
I suspect they come from the same place that IMS superstock pegs come from????
I think it would be silly to Pay $90 for the IMS pegs when these are very dependable
