All-rounder | Can be used from standard PX200 to 260 cc; wide setup window |
---|---|
Pre-reso | Very good pre-reso performance; early torque and everyday pulling power |
Overrev | Wide band with long overrev; high cruising and top speeds |
Throughput | 32 mm tailpipe; thermally uncritical even with powerful setups |
Sound | Powerful and pleasantly muffled; sporty without shrill tones |
Wide tires | Suitable for wide tires; very good ground clearance due to left-hand layout |
Workmanship | Turned flange parts, solid clamp (optional spring), clean weld seams |
Maintenance | Touch up the paint layer as required; long-lasting operation |
Painted steel Lefthand design Mature classic (25+ years) Strong pre-reso performance Wideband & overrev 32 mm tailpipe Very good ground clearance Wide tires possible Plug-and-play Attractively priced
The RS-Series is a mature classic: originally developed for the Malossi 210, today it is a real all-rounder - from a complete standard engine to 260 cc Quattrini or VMC. It offers very good pre-reso performance, combined with strong peak power and a wide rev band/overrev for powerful PX200 setups with a sporty gear.
Early punch through pre-reso, powerful in the middle, very easy to rev at the top. The long overrev keeps the power high after the peak and enables high cruising and top speeds. The 32 mm tailpipe ensures throughput even on thermally demanding setups. The sound is powerful and pleasantly muffled.
- Can be used from standard up to 260 cc (e.g. Malossi/MHR, Polini 207, Pinasco, Quattrini, VMC).
- Standard carburettor possible; depending on the setup, a larger carburettor/intake tract may be advisable. Clean jetting and ignition check recommended (spark plug pattern/EGT).
- Do not select a primary that is too long so that the engine can rev freely and the overrev can be used.
Plug-and-play
at the original points in Lefthand. Install tension-free, set sealing surfaces cleanly and retighten screw connections after 50-100 km. Spare wheel cannot be combined; in return, very good ground clearance and suitability for wide tires.
✅ Exhaust body: Steel, heat-resistant paint (black)
✅ Tailpipe: 32 mm (high flow rate)
✅ Design: Lefthand, without spare wheel
✅ Character: Strong pre-reso, wide bandwidth, long overrev
✅ Application: Vespa PX200 / P200E (depending on model/setup)
Turned flange parts for precise fit of cylinder and manifold connector.
Solid clamp on the flange, optionally with spring suspension for vibration decoupling.
Clean weld seams, precisely fitting brackets; paint can be easily touched up if necessary.
Corrosion protection | Protection via heat-resistant paint; repair stone chips promptly. |
---|---|
Thermal | Good thermal conductivity; 32 mm tailpipe reduces thermal peaks. |
Maintenance | Paint can be easily repainted; regular visual inspection recommended. |
Repair | Welding work generally uncomplicated; seal paint spots afterwards. |
Price | Often cheaper than stainless steel with comparable performance. |
Very compatible with Malossi MHR, Polini 207, Pinasco as well as Quattrini M232/244 and VMC Ranger 213 or Explorer 244. Moderate-sporty timing and no overlong primaries help to make full use of the overrev.
