Did you mean the yellow S4 challenge? If so, those aren't clip ons as such but the original standard bolt on handlebars and are similar in position to the normal monster bars, but not adjustable. Easy to switch over to the standard bars but you will need to fit an 900/1000/S2R/S4R or aftermarket top yoke. The radiator is a matter of taste, I don't mind it and the extra performance of having the 4 valve 916 motor over the slower 2v. I've just fitted clip ons with risers to mine and its much better for it imho and not radical like a sports bike would be either.
