SIP Vespa racing cylinders
Engineered for Vespa 50-125 cc PV/ET3/PK/S/XL/2 LongFrame models, these SIP Performance racing cylinders in grey cast iron feature six overflow ports with 55.6 mm bore and 51 mm stroke, 8 x 8 mm stud bolt pattern, with 52 mm hole spacing and long thread spark plug design.
High-performance cylinder kit in the 125 cc class for Vespa SmallFrame models. The SIP Performance cylinder helps the small Vespas to achieve modern performance in the popular displacement class.
The modern layout of the overflow system makes it possible to achieve significantly better performance than with the original 125 cc cylinders used in the Vespa SmallFrame models. There is a modern-style channel layout with large cross-sections and high quality two-ring flat pistons and four gaskets.
The original Vespa SmallFrame engines only deliver 5.6 hp and 85 km/h. With the SIP Performance 125, the achievable power is on a par with the 133 cc-136 cc grey cast iron tuning cylinders that have been widely used since the 1990s.
These cylinders fit without modifications to the engine case and have a 118-degree boost port, 178-degree exhaust and 122-degree overflow.
"These are the perfect contemporary upgrade for SmallFrame Vespa engines," says CEO Ralf Jodl. "Our tip for the best set-up would be to add the SIP road banana, SIP engine case and SIP Performance ignition."
