Exhaust M244 Righthand - Steel

Special version of our exhaust system for Quattrini 232-260cc engine setups with Vespa PX 200 engines in right-hand design: We build our exhaust systems entirely by hand in our Vespa workshop in Bispingen near Hamburg - the right-hand exhaust for Quattrini is currently only available in stainless steel, optionally with our S PLUS noise insulation or uninsulated.
The Scooter & Service Righthand exhaust for Quattrini M232-260ccm fits all Vespa Largeframe models and is not suitable for use with a center stand; the angle of the silencer can be individually adjusted upon request - the standard angle is suitable for Vespa PX models.
The performance of this exhaust system is identical to that of our left-hand systems for Quattrini 232-260cc cylinders.
The exhaust system is of course supplied including all necessary mounting parts, brackets, etc.

Vespa racing exhaust Scooter & Service Quattrini 232 - 260ccm

This Scooter & Service Vespa racing exhaust was specially developed for the Quattrini M232/M244 cylinders and is characterized by an enormous range with very high torque even from low engine speeds.
The exhaust is suitable for both rotary valve-controlled Vespa PX 200 engines and reed valve intakes, and runs very well with port timings of approximately 128-130° / 27° exhaust lead. Since the Quattrini cylinder is supplied with very short port timings as standard, we recommend using the M232 cylinder in conjunction with a 60mm crankshaft and a correspondingly thick base gasket.
The PX 200 racing exhaust for Quattrini cylinders, like all Scooter & Service exhaust systems, comes with CNC-machined flange connections with Viton rings and all necessary mounting parts - the exhaust is available in steel or stainless steel and with or without noise insulation and is suitable for both center stand and wide tires.
The diagrams shown of our test engines were both created with an exhaust system featuring S PLUS internal insulation; both engines are equipped with a crankshaft with a 60mm stroke – a reed-controlled setup with a 64mm stroke is currently being planned.

Vespa racing exhaust - noise reduction

All handcrafted Scooter & Service racing exhaust systems are optionally available with our developed noise reduction system "S" or "S PLUS", which reduces the noise level to TÜV-compliant values ​​and, above all, harmonizes perfectly with torque-oriented Vespa tuning solutions.
In conjunction with the 244ccm setups from the manufacturer Quattrini, this results in high-performance and high-torque configurations with exemplary running characteristics and a very civil noise level.
