VMC Ranger cylinder - 213/225 cc for PX200 Touring setup with early torque
Ø69 mm
213 ccm (57 mm) or 225 ccm (60 mm)
7 transfer ports
118°/176° head angle
Viton O-ring on the head
4-fold exhaust flange
Made in Italy (Gilardoni)
Highlights
The VMC Ranger is a touring cylinder with a sporty design for Vespa PX200, Rally 200 and Cosa 200. Large scavenging surfaces ensure high filling, while the moderate steering angle delivers early torque and Vespa-typical power delivery in the practical speed range.
Concept: more pulling power without being heavy on revs
As an alternative to the Malossi Sport 210, the Ranger is aimed at a setup that works in everyday use: clean transition from the cellar, strong acceleration from medium revs and reserves for long stages. The large ducts respond clearly to optimizations to the intake and exhaust system - without the character tipping in the direction of "top-end only".
Intake and crankshaft
A standard SI24 carburetor is perfectly usable as a basis. If you want to exploit the potential of the cylinder to the full, a crankshaft with an extended intake angle makes sense, because the Ranger benefits noticeably from more effective intake time.

Setup note: 57 mm or 60 mm
Thanks to the spacers supplied, the Ranger can be ridden with a 57 mm or 60 mm long-stroke. 60 mm slightly increases the displacement and the steering angle - in practice, this results in noticeably more thrust without losing the touring character.
Tip: For long-stroke setups, check the trailing edge, compression and ignition timing carefully to ensure that the thermals and rideability are right.
Recommended exhaust combinations
With 118°/176°, the Ranger harmonizes very well with box exhaust systems, for example Polini Box or BGM Touring Box 2. This keeps the power delivery broad and suitable for everyday use, with powerful torque in the middle.
Exhaust design: leave it as it is
The Ranger has a specially shaped exhaust port with convex curvature in the upper area. This shape is aimed at a round torque curve and good acceleration. VMC recommends not to modify the exhaust because changes can shift the balance of torque, temperature and smoothness.
Cylinder head and cooling
The aluminum cylinder head with radial cooling fins is designed for stable thermal performance. The 8-point screw connection supports even contact pressure, the Viton O-ring seals the combustion chamber cleanly. The central spark plug position ensures short combustion paths and even combustion.
An SI24 is sufficient as a basis. More potential comes from a clean tuning and a harmonious intake and exhaust setup. Larger carburetors are possible for maximum performance, but are not a must for concepts suitable for touring.
57 mm is the uncomplicated basis with a very wide band. 60 mm provides more displacement and generally more pressure - it is then important to control the squeeze edge, compression, jetting and ignition properly.
Not recommended. The exhaust design is matched to the overall package. Changes can impair rideability and have an unfavorable effect on thermals.
Designed for Vespa PX200, Rally 200 and Cosa 200 (Largeframe 200). Standard connecting rod length 110 mm is supported.
Conclusion
The VMC Ranger combines large scavenging areas with moderate steering angles, making it a cylinder for riders who want significantly more torque but still want to be able to tour. In a suitable setup (clean tuning, harmonious box exhaust, sensible intake), it delivers a wide power band for the PX200, Rally 200 and Cosa 200.
