If your getting hwy bars/crash bars mainly to have footpegs then another option to look at is MC Enterprises. They make lower profile hwy pegs for the M50 that don't require you to have the crash bars. I have them on my bike and I am quite satisfied with them.
Not on my computer right now. I can take some this weekend and post them. I'll try to do that. In the meantime go to mc enterprises website and select "products" at the top. On the left hand side fill in your bike info and choose Deluxe alligator pegs and it will take you to a close up pix of what it looks like.
