Brand New — never installed! CNC billet aluminum crankcase half (“Mullet” series) — the second / matching half to the previously sold one. Precision machined from solid aluminum billet with polished finish and “mullet” engraving. Important: This is one crankcase half only (the cleaner side without the extra side bracket). No bearings installed on this half. Designed for high-performance Minarelli horizontal 2-stroke engines (big bore compatible). Fits: • Yamaha Jog, BWS, Aerox • Honda Dio AF18 / AF27 clones • Most Chinese horizontal Minarelli-style scooters
