Review on Universal 2-Piece Split Clip-Ons Assembly With Adjustable 7/8" Bars And 45Mm Handlebar Diameter - Ideal For Cafe Racers And Motorcycles by James Womble

Unlike the more costly ones(image on right) which split so that the top off the triple clamp does not have to be removed to install them these do so the install is much more involved.

I would not take of points for that as you get what you pay for. In this case after removing the stock bars and removing the top clamp I found they did not have enough rise to clear the faring so while they did technically fit they are not usable.
