For sale; Brand new Performance Technology adjustable clipons, 53mm clamp size and designed to fit 1098/1198 and probably more with that size top fork dia. I attempted to fit these to my 916 but the front brake reservoir did not allow enough screen clearance for fitment, hence their sale...they are top quality Italian made aircraft billet alloy items and allow for back/forth and up/down degrees of adjustment due to the eccentric design of the bar to clamp arrangement...looking for £90 posted.
