yes, I have these. the kit comes with the pieces that fit into triple clamp that look like the bottom half of the bars, 2 spacers for each side of different thicknesses and the bottom cradle for the bars to fit into. you use the stock top clamps. if you use no spacer, the bars are raised approx. the thickness of the bars themselves. you can also use either or both spacers for more rise. you get 3 sets of different lengths of chrome moly allen bolts, too.
because they're made for dirt bikes, they're not as "pretty" as the one piece Gen-Mars, but they're not $75 either. it's a cheap way to see if you like your bars raised. you can always sell them to a dirt biker if you want to go "stylish" later.
