The RS-Series 2.0 is strictly designed for high-end tuning. It is aimed at high-output 177-206 cc cylinders with adapted control angles and develops its strengths on setups such as Quattrini M1X/M1XL, revised BGM177 concepts, Malossi MHR and Pinasco 206.
Early, defined use, strong mid-range and pronounced upward revving. The long overrev keeps propulsion stable after the peak - ideal for ambitious gear ratios and high top speeds with suitably prepared engines.
- Target geometries: sporty control angles (e.g. overflow angle > 120-130°, exhaust angle ~ 180-195°, depending on setup).
- Peripherals required: large carburettor/intake system, flow-optimized intake (diaphragm or heavily reworked rotary valve), powerful ignition (preferably variable), stable clutch/primary.
- Do not select an overlong gear ratio so that the overrev is used effectively; clean jetting and temperature/ignition control are mandatory.
Plug-and-play at the original points. The manifold is spring-mounted on both sides, the cross-member bracket is vibration-friendly. Install stress-free, align sealing surfaces precisely, retighten screw connections after 50-100 km.
✅ Design: Lefthand, main stand suitable, wide tires possible
✅ Tailpipe/layout: designed for high throughput and temperature reserves
✅ Materials: Stainless steel; clear-coated steel (corrosion protection, not heat-resistant)
✅ Manifold: spring suspension on both sides
✅ Application: Vespa PX80 / PX125 / PX150 with 177-206 cc high-end tuning (depending on model/setup)
Voluminous, precisely fitting body with clean pipe routing; stable crossbar holder for low-stress installation.
Turned flange parts for precise cylinder fit and tight manifold plug-in connection.
Solid clamp; optional spring suspension on the flange for vibration decoupling.
Recommended with Quattrini M1X/M1XL, revised BGM177, Malossi MHR and Pinasco 206. Select sporty timing (e.g. overflow > 120-130°, exhaust ~ 180-195°, depending on target). Large carburetor, flow-optimized intake tract, precise ignition and jetting work as well as a suitable gear ratio are prerequisites.
