Clubs that are considering a successor to the Honda CR125 for long-circuit work tend to ask the same practical question first: which package can the membership actually keep on the grid through a full season, not which engine is quickest over a single lap. The options members raise most often are the KZ shifter and the IAME 175 SS or SSE. What resolves it for most groups is parts availability and the real cost of keeping a gearbox engine within the regulations. Newer members often treat the two as interchangeable shifters and underestimate how different the homologation files are for volunteer technical inspection. One further issue worth weighing is that leaving both eligible can hold a grid together, yet it may also keep the used-engine market from settling at the moment a club most needs a clear parts path. How have other regions found durability and season cost on each option, and has one of them become the default?
