Cylinder kit POLINI Sprint Veloce Ø63 PIN Ø15 Vespa 125cc-> 2T

Key strengths of this new Polini kit:

• Cylinder diameter 63 mm. Designed to improve gas flow.
• Available with standard 57 mm stroke for 178cc, or more Racing with modified 60 mm stroke for 187cc. For the 60 mm kit, an advanced crankshaft is available.
• Air-cooled cylinder, but thanks to aluminum and special fins, the engine temperature stays lower.
• New cast cylinder head, prepared for two spark plugs. The classic side spark plug hole, like the original, is easiest for assembly; the Racing version with central spark plug requires a small modification to the plastic cover.
• Extra mounting points: not just the standard 4, the Polini head has 4 more for better compression stability.
• Enlarged fins for improved heat dissipation and silicon steel cylinder head gasket (not on the original Vespa) for maximum compression resistance between head and cylinder.
