These are the best feeler gauges I have ever used. They are the only set I've seen that is capable of measuring 2-4v Ducatis. They are half the width, yet are longer than any of other feeler gauges, making them perfect for getting into tight spaces, such as on Testastretta engines. The 14 piece set includes gauge sizes as follows: .002" (.051mm), .003" (.076mm), .004" (.102mm), .005" (.127mm), .006" (.152mm), .007" (.178mm), .008" (.203mm), .009" (.229mm), .010" (.254mm), .011(.274mm), .012" (.305mm), .013" (.330mm), .014" (.356mm). These are the feelers I use on all Ducatis that I service.
