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 crosssections 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 ."
