The O.S. Speed 21XZ-B Spec. III With T2060 features a newly designed crankcase and piston and cylinder and its displacement still remains at 3.49 cc (and not as 3.46cc like the Speed B2101). The engine head is 5mm lower than spec.II for lower gravity. Last improvement, the 3-port exhaust makes air flow effective after combustion.
