Warning : it is mandatory to fit the 44 mm stroke crankshaft code 210.0069 (the combination of thermal unit/crankshaft allows you to reach a displacement of 93.4 cm3
, getting
an increase in displacement equal to 88% compared to the original)
Attention : it is mandatory to replace the clutch springs with the reinforced springs 228.0105.
Warning : it is recommended to evaluate an extension of the final ratios (crown/pinion) according to the use of the motorcycle
