Malossi Big Bore cylinder I-TECH 4 STROKE 183cc
Malossi is steaming up the new Piaggio 3 valve engines!

About 183cc are achieved by widening the bore from Ø52mm (original) to Ø63mm.

This gives the engine much more torque and driving pleasure. As always with Malossi, the life span of the engine is as good as the original thanks to very good material selection and processing. According to the increased torque of the large cylinder kit, owners of a 125cc version should use the clutch and converter of the 150cc version (see accessories). These are much more stable and larger in size, thus improving not only the transmission ratio range but also the touring capability. The ForceMaster module adapts to the new injection requirements, but can also be adjusted individually (+/- 20%). The module automatically raises the speed limit of the integrated speed limiter by 1000 rpm. The module also has four fixed pre-programmed mappings.


Technical data:


  • bore: 63mm
  • stroke: 58.6mm
  • capacity: 182.6ccm
  • cylinder: Aluminium cylinder with ultra-hard Nickel-Silcium-Carbide coating (therefore very good heat dissipation, short warm-up phase, and very long service life)
  • The original cylinder head is retained
  • Incl. ForceMaster module
  • Complete, ready-to-install kit


NOTE: Due to the different throttle valve types (with integrated CDI and without) Malossi offers two different cylinders:
