I put them on my SM on Sunday, and am pretty happy with them. Quality is very good and they are solid. I got the mirrors too, which work well despite the small size, and help clean up the front end. The handlebar top clamp is a pretty close fit with the dash, and partially obscures the view of the dash (specifically the warning light that cuts max power for heat management). A couple of installation notes: HDB says you can drive the tap for threading the inside of the bars with an 11mm 12-point socket, but I found that the socket slipped under the torque required, and ended up buying a large tap wrench that could fit the tap. Also, if you get the big bolts for the bar end, they take a 9mm allen drive, which is an uncommon size. I had to make a trip to Sears. Other than that, everything is pretty straightforward.
